Converting Rails Site to WordPress/Member Based Site (PHP)

I have a member based site that matches up available housing with college students . It was built in Rails. It's totally functional, but does not allow for easy updating of pages without a Rails developer involved. I prefer PHP. Here's what I'm looking at: 1.) Taking current design and converting to WP Theme Templates. (4 Front end). (Backend Administration - 5 templates/layouts) 2.) Combining with a member based system such as Amember or a custom system designed in .php. (You will have access to all Rails code and html layouts.) 3.) You may find that this system works best with WordPress MU. Perhaps BuddyPress would be a nice plugin. I can give you the URL via PMB so you can see the entire site. First, please provide me with URLs of 2-3 member based WP sites that you've worked on. My budget is around $900-$1,200. I would want the site conversion completed in 15 days.
