I am the top ranked Freelancer on Elance for XenForo and VBulletin work. I can pretty much get anything done with either XenForo or VBulletin that you can think of. I have 7 years experience administrating, customizing and developing addons for forums.
I also own three forums including one members only forum. I also have extensive experience in running a paid community with membership based off Paypal. I have worked extensively with the Paypal Recurring Payments API.
