Very nice work and quite an artistic flair I might add. I was impressed by the owl and the dino. Both are very good quality IMO. You have a good idea for starting a business. Something that you might want to keep in mind is that this is a customized business. Your customers will vary and so will their needs/wants. The customer base building will be a little tricky however it can be accomplished with a little bit of tweeking.
In starting any business, a focus should be on where your main market is going to be. This is probably one of the most difficult for any new business owner. Once you've figured out what your primary market is going to be, then you can start to focus on getting your clients. Since I'm seeing a lot of children's murals, I would safely assume that is the chosen avenue.
Next is to set up a portfolio of your completed work before you start marketing and advertising. You have to show what service you can provide others in order to sell. There are a few ways you can do this. One of which is to take photos and build a photo album of them. You could purchase a nice photo binder to display them in and start filling it with your creations. Another option is to take those same photos and put them into thumbnails onto a web page with a small description about the mural. Descriptions are always nice with photos because it highlights the visual to the reader and adds depth to it.
With marketing and advertising there are many options available for spreading your business name out. One of which mentioned was word of mouth. Another is use of a flyer or a brochure with a photo of a mural on the front of it. Inside the brochure you can have details about the business itself with more information about the business, what type of murals you provide, etc. You can become involved with networks and talk to other business owners about building your business. In cases like this, you will find other people have gone through similar situations or are currently experiencing it. Networking is one of the most helpful ways you can build contacts with others. Grant it that you may not get clients, however you do tend to gain quite a bit of knowledge in business operations.
I've been building on a network (actually a few) since I started working on my consulting business and have met quite a few people. My effforts have paid off and my name has gotten spread around about the work which I perform. The web is flooded with advertising and competition. At the same time, when you're involved with a small circle even if it is for support and guidance, it does make a world of difference - at least in my opinion.
I'm not sure if your wife would be interested, however there are a few women business groups that I am involved in. If she would like to join them, they're free sign up. If she does have interest, let me know (
