Ask HN : Building a marketplace for developers. Features?

I'm building a marketplace where people can get qualified developers to work on projects/bugs. And if you have a project/bug that needs work you can find someone on the site as well. The idea came out of people asking me multiple times to "just fix the problem, i dont want help, i'm willing to just pay you to do it". As developers what do you think is missing from the Elance/Odesk type of sites? As project submitters/bugs what would you like to see as features.<p>Every project on my site will be required to be pre-funded ( money sits in escrow ). Devs sign up through Github or Bitbucket.<p>And if you're interested in the beta : http://signup.codefix.io/
