You either get a pointer or a flushing dog...you don't get both (*** well kind of, but more on that latter, but that statement holds true for birds***). The 1k mark will set you up with a nice puppy from moderate to good hunting lines. You won't touch a good started dog for 1k from any reputable breeder.
You don't train a dog to hunt. They are either born with or without that ability, you take that risk with any puppy you buy, although good breeding generally helps alleviate any concerns about a dog that won't hunt. That being said you run the risk of a puppy not having any hunting drive, it happens even from the best breeding lines. Training simply harnesses a dogs ability to hunt for you and not for itself.
Ask yourself what you will be hunting, where you will be hunting, how you like to hunt, and what kind of temperament you have and want the dog to have. Do that before thinking about what breed you want.
I would try and find a trainer that will let you do weekly sessions with your puppy and tag along during the training. You can learn training methods from someone that knows what they are doing and train your pup between sessions yourself.
Gear; 50 ft check rope, 100 ft check rope, whoa boards, garden posts for check rope whoa training, bumper, training blanks or starter pistol *****E-collar ****don't do anything with an E-collar until an actual trainer shows you how to use it, nothing ruins a dog quicker than and idiot with an E-collar.
My personal experience is on the pointing dog side of things. So i'll tell what I know from training/hunting my dogs and hunting with other peoples dogs. I mostly hunt grouse and woodcock, but usually make a couple trips to the MW for pheasant and quail. I'm a GSP owner who wishes he had gone with Brittanies, Llewellyn pointer/English Setters, or Brittanies. GSP's are fantastic dogs, but like all German bred versatile hunting dogs GSP's were bred for hunting multiple animals. That means in addition to fowl they have a high prey drive for rabbits, boar, deer, badger, etc... This is the exception I was talking about. GSP's were bred to point birds but actively run fur game, much like a hound would. This gets really annoying, especially hunting areas with few birds. They get bored easy and start hunting any fur they can get their nose on. This is something that will go away overtime but for the first 2-3 seasons they will have a ton of fur drive.
Training has it's place, but there is no better trainer than hunting seasons and bird contacts. If you have a dog that isn't understanding whoa...let that dog bust a couple points out hunting. They will figure it out pretty quick that their role is to find the birds and your role is to knock them out of the sky. I didn't believe it at first, but at the end of her first actual hunting season my problem dog transformed into a bird pointing machine.
Dogs I have hunted over and my observations in general;
GSP's, GWP, Drahthaar Pros; very smart, willing to pleases dogs, good noses, very athletic, they cover lots of ground, pretty good natural retrievers, love the water, very strong swimmers, and very adaptable to different birds. They can hunt pheasant one day and hunt grouse the next without skipping a beat. Pretty forgiving from a training perspective. You can hunt them in hotter temps than longer haired dogs. Some dogs can be sensitive and shut down if they feel you are getting frustrated, others take correction in stride as long as you don't go off the handles.
Cons; The first 15 minutes they are useless. They get so hyped up they spend the first 15 minutes running around like crazy, shitting and pissing all over the place because they are so keyed up. No matter how disciplined I've been with exercising them, they always have that pent up energy for the first 15 minutes. Once that's out of their system they are good. They get cold, really easy, anything under freezing the vests come out. They tend to not be cover busters and check hunt. What I mean by check hunt is they will smell key parts of cover and if they don't smell anything interesting they move on to the next bunch of cover. Very efficient for covering lots of ground, but they will miss birds if the scent is not fresh or scent conditions are sub par. This happens a lot with pheasant. you will get a runner that heard the truck door close and the dogs will get birdy where he was laid up, but he's ran so far away that the scent trail is next to nothing and the dogs won't cover bust unless they have a strong scent. Like I mentioned earlier GSP's have a ton of fur drive. My girls have killed coyotes, badgers, and damn near took down a deer, all before I had the chance to get the whistle out of my pocket.
Brittanies.
Pros; Love hunting behind a good Brittany. They hunt a little slower than GSP's (which I like YMMV), excellent noses, I've never hunted behind a Brittany that was known for missing birds. They are cover busters, no thicket is too thick for them. Very thorough hunting dogs. Good natural retrieve. They can hunt down to around 10 degrees without issues. I love the disposition of Britt's. Good natured dogs, willing to please, if you get a little frustrated they shake it off, great dogs. They don't have as much fur drive as GSP's, occasionally they chase after a bunny, deer, or point a mouse, but that is about as far as their fur drive goes.
Cons; Their coat needs maintenance. Every thorn, sticker, etc... gets attached. They get hot pretty quick, even when shaved. Not the strongest swimmers. take a little transition time between different birds. Dogs that are use to grouse take a few trips to figure out they need to block or pen a pheasant so they won't run. Lastly they don't have the endurance of a GSP.
Llewellyn pointer/English Setters;
Pros; They hunt somewhere between a Brittany and a GSP speed wise. Same thing with cover, not check hunters, but not big cover busters either. Good noses, maybe slightly better than your average Brittany. Good swimmers, good endurance. They tend to be strict bird hunters, not tons of fur drive.
Cons; Their coat needs maintenance. Same issues with heat as with a Brittany. My only major complaint and why I will steer you away is; they are very moody and sensitive dogs. They take a very calm, experienced trainer. They can be stubborn and if you get frustrated and let it show they will shut down. If I ever was to get an Llewellyn or ES I won't use an E-collar on one, they need a very soft hand and even tempered person.
