All the answers here have been from the point of view of an artist. Harsh or not. Maybe you need to step back and look again from the point of view of a business. If this conversation were about something other then "our work" (which we are all passionate about) would you want to invest your money or something more valuable, your time.
I would suggest you map out your goals and make a business plan just as you would any new business. Know what you want from it, and what other's want from it. Maybe its not the best thing for you. Maybe doing your own thing might give you the most return on your time.
Just a quick couple of thoughts,
