Buddypress Modifications

Make modifications to an existing Buddypress MU site. Project Requirements: 1. Create 3 custom registration pages and 1 custom log-in page for Buddypress. We have created a multi-step process wherein the user registers, and answers a series of questions in the process. I have all these pages ready in photoshop, with all the images and text layers. 2. The person's email address will serve as their username to log in after registration 3. Adjust all site pages, including log in and register, with a liquid layout, so that width and height automatically re-sizes on all screen resolutions.
