Well as usual starting aka the beginning is always the hardest part in anything, I suggest you gather some pretty decent streetballers who arent just fakers (real ballers) and start to play together, then come up with a name, logo, etc like youngtricker said afterwards to make you the local best team you gotta challenge lots of people and need to win those games if you want your name/team name to be heard by people, then join competition/contest and preferably win it from there you will get notice by sponsors then with luck you would be recognized and someone may one to sponsor ya...
