OP, you said you don't need a kit for combat wounds, just regular boo boos while hiking. Making your own is definitely the best way to go. Go to the dollar store,get band aids, triple antibiotic ointment, and whatever sundries you would like. Maybe supplement with somethings from CVs/Walgreens that thedollarstore may not have. Put it in a ziplock freezer bag, then find whatever surplus molle pouch that is cheap, and you're good to go. You said you need five kits, so this is definitely the cheapest route. If you really feel the need, you can add an Israeli Bandage or the like. Maybe a TQ. Whenever I have gone camping, bandaids and neosporin and tape cover most of my needs.
I like to buy first aid supplies from Rescue Essentials (no financial interest) because they have bulk packs that are perfect for what you are describing. You can get ten packs of single use triple anti biotic ointment, simple analgesics, antiitch creams etc.
