Amember payment Integration

Hello all, I am launching a new website and will be using amember as the membership script. Amember already has some great plugins for payment systems, but I plan to use some new billing system that are not currently integrated into amembers billing system. Billing systems I wish to add: [login to view URL] [login to view URL] Bitcoin Therefore I need a developer that is an expert at amember and can integrate these billing systems. Ideally I would like a user to visit my website, decide to join and see the available options; dwolla, noca, or Bitcoin. The user chooses the option he likes best, completes payment, then is granted instant access to a 30 day period. Amember already does most of this, what I need a developer for is the billing platform integration. Thank you!
