we are a pair of (recently laid off) developers working to build a better classified ads application than those in the local market (you should see them, they are mostly god-awful). unfortunately, we don't have much designing chops, so we turn to the community to help us out on this matter.
our main target audience is real-estate brokers. the features of the site will attract these users to open accounts, but we need the logo to initially hook them. with one image we can let them know what the site is all about. the rest of the target audience are regular users shopping around for houses, cars, electronics, books, etc. everyone appreciates a little eye candy.
