Hello, I could develop this site on VB.NET using any DB in the background. I can already imagine the site and some functions that you haven't included in your description (like searches by any field, direct link to the project that you want to refer to, direct link to the freelancer in the freelance site, rating of scammer freelancer, reports, etc). My bid already includes your requirement and any new feature that I could create for you; so, I'm assuring you a good quality job and innovation.
Looking forward to working with you,
Thanks for your time,
Leandro
