You could use this as an opportunity to promote the site. Post the need for a logo and other related things to similar sites you mentioned in your post above and ask for help. People on these sites will not only see your post and be able to help you, but will also become aware of the site and might consider listing their services.

I'd also recommend to read about how Craigslist, Kijiji, AirBnB and similar sites grew. I believe some of them simply listed on their competitor websites.

Btw, I tried the site yesterday. The loading time was really long and the side bar on the right hand side got stuck and wouldn't move anymore after a couple of seconds. I'm not sure about the stage of development the site is in, but is it too early to visit, use and promote the site?
