There's no explanation of what you want there, and I'm uncertain what to enter (dollar amounts of the min/max project I'd consider working on? I'm not sure I could provide useful values here). Some help text or suggested answers would be useful.
[the whole idea of social network as resume enhancement unnerves me, also; I'm comfortable with the idea of potential clients looking me up on FB &c, but I don't want to shove my profile directly in their face. But that's just me being squeamish about these things]
It would also be good to make it clear through the profile-filling process that there is a separate section for a portfolio. I was trying to work out where to fit in mention of things I've worked on.
