What your site really needs is a good design, proof read text and serious terms and conditions. Then you can think about more products, because as it stands, as a developer I have no incentive to use your site at all, unless I wanted to ruin my own reputation.
Also, a tk TLD?! You can't be arsed to spend $12 to buy a real TLD?! Why should I be arsed to spend money on a site that bombards me with advertisement and looks like it was made by a twelve year old after their first HTML class?

Don't get me wrong, the idea is good, and there certainly is a market for this, but the execution is terrible.
