The site is down now, congratudolences. :)

I have some experience building a market, although not with consumer goods. Reading about AirBnB's initial work, and also from talking to investors at Rover, getting one side or other of the market together is always where the work is.

For AirBnB, apparently, it was listings. For you, that might be the case as well. Seems like the next step might be to hustle, hustle, hustle and figure out how to get a lot more equipment listed. I know for sure I'd rent a Mamiya 7 or a Leaf or a Leica M-Monochrom in an instant if it were out there.
