Well, at the time of my post you had an istockphoto image with the watermark still on it in your header, and your blog link still doesn't lead any where, compete didn't list you and Alexa ranked you somewhere around 5 million. I still think my logic is sound.
If you really do have your own network of advertisers then that's great, you're off to a more impressive start than a lot of other ad networks, and I've seen my fair share of them.
I'd still recommend people to be a bit wary, but if you could provide proofs of your network size then that would probably help a lot of people make the decision to join, I'm all for going with start ups, but one just needs to be careful.
As for winning me over, I currently serve well over a million ad impressions a day, so I simply cannot afford to go with an untested provider as that could result in a significant loss of revenue. This probably also puts my "hardly any visitors" claim into perspective.
Best of luck with your business, though, it's a really tough one to succeed in and you'll need to be aggressive in the right way, most big sites do not pay attention to marketing emails any longer, I certainly ignore almost all sales emails.
