I agree with what every one else has said, however, I have one other thought to add. If you have friends who are going to specialize in producing, that is really good, because I say that most of the big DJ’s out there (at some point or all the time) make their own signature music, and I personally think that making your own music as well as DJ’ing it, has the makings for success and respect.. Not that I am saying for the pursuit of money, but how rewarding would it be, to mix up the music you helped create… awesome…
I say, if you can work with these other people, you will be better off working together than working alone, not to mention being able to keep each other motivated, because DJ’ing can be really frustrating at times.
Good luck
