Well, I was talking to a friend about this, and we did decide that the majority of customers would come from that situation. Personally, I buy/sell a few domains, I wouldn't go as far as saying I'm a domainer but I enjoy buying and selling them, but whenever I see anyone with under 5 iTrader I tend to steer away, even though quite a lot of the time it's those people who sell some really good domains, but I just wouldn't trust sending $50 to them. That's the sort of situation where my services would come in most handy, I think.
you should try and see may be it'll go better than you thought, or worse.. whenever I have a project in my mind I do it
