You're both 17 and shoot pictures as good as those? Why not start a business? Well, one thing is that you're both not 18. You might want to check your state's biz regulations as to what the legal age to start a photographic business. But, in all fairness, I'd say go for it. You may also have to get a city and state business licenses, go to the bank and set up a business checking account, register your business name, get insurance, start business plan, put together contracts for your clients, or it they are underage, their parents to sign, set up a price sheet for various packages and al la carte orders. And another thing, you 'll have to start charging your customers a state sales tax, because the state will want their cut as well. So it's best to hire a CPA to figure out all that stuff for ya.
Taking pictures on the side is one thing, but starting a business, is another. You really, really need to educate yourself in all facets of business, not just the photography side. Taking pictures these days is the easy part. You might want to get your parents involved in this venture.
