WPMUDev Membership + Gravity Forms or Custom User Registration

I would like someone who is proficient in PHP and has experience with the WPMUDev line of products to do some custom coding work for me. Ideally, I'd like to integrate Gravity Forms (I have the dev version) with WPMUDev's Membership plugin. If that isn't possible, I would need some coding work done to make WPMUDev's Membership plugin accept custom user registration fields. I'd like you to advise me on the best possible course of action to do what I need done. Here is what the support staff at WPMUDev has told me: there's a couple threads here which might help [login to view URL] [login to view URL] alternatively, you can use buddypress which has it's own custom fields system using x-profile which does work with membership. you don't actually have to use the rest of the buddypress features, just use the x-profile custom fields.
