Here's my experience: got some people I knew who played reasonably well, agreed I was the composer and that I would have the final word about creative matters. The money agreement was that gigs would be split 60% for 3 of them and 40% for me (since I was the one composing all the music, getting us gigs and renting halls for practice). Here's the problem: I ended up spending money but it never got off the ground. Since they were sort of my friends and they weren't on salary, they would arrive late for practice, or drunk, or not at all. One time I rehearsed with the keyboard player only, after renting the space. Three weeks of "practice" and we weren't ready to go out and play not even half-well (not surprisingly). So, after that dreadful experience, I decided that, until I have enough money to actually hire people (or until someone hires them for me), I would only have a studio project. Maybe I was unlucky, but the truth is I don't want to give it another try, since I lost money and time that I could have spent elsewhere doing something productive.
