I had a project a while back and he approached me wanting to do it. He gave me his phone # and I called him and he didn't even remember we had talked on here in pm's. I thought it kind of odd as he said he wasn't that busy and could probably start that same night or the next day. He seemed really pushy and I got a very uneasy feeling about him. I had already decided to not use him and he kept calling back and leaving messages and I knew I'd made the right decision. Of course the person that I did use never finished but at least never charged me anything up front. Tim wanted to charge me half up front. My suggestion to people is to get a phone number and talk to the coder and it will help you with your decision. It worked for me or either I'm just lucky...
I do know he contacts people to offer services and the admins should step in and keep him from doing this no matter what it takes. I'd do so on my site.
