Unique Auction Programmer

I am looking for a programmer to finish a website. I know what needs to be done on my project, but, I am looking for a programmer that will tell me what they see wrong and what they will charge to fix it. I will put the payment in PayPal or an escrow and will not pay until the site is completely finished. I have hired two programmers who said they did. I paid them both, and waited months for the finished product which I never received. I am sorry I have to be so skeptical, but I have learned two hard and costly lessons. If I find a programmer I can trust I have more projects to get up right away. I might also be interested in a partnership if I find the right programmer.
