I tried something like this, but instead people would just take take and submit video of a problem they had with one tap (the noise their car is making, the leaky faucet, showing and telling what interior design work they need done in a house etc). The idea was to let businesses see the videos for free but make them pay if they wanted to contact the customer.

I got no takers on either side - no one submitted videos and, if they had, I had no businesses interested in viewing them. These marketplace ideas seem like better businesses than they are. I'm convinced that the only successful ones will be those that are hyper-focused on a single niche. "Oh that's the app/site I open if I need X" instead of "I can get anything I need from this app/site". It seems that consumers just don't like having too many options from a single source (with a few notable exceptions, but it is effectively impossible to become one).

Good luck with yours though - I am just sharing my experience.
