To answer your questions:
My Location: Toronto, ON. Client: Orange County, CA. Designer: San Fran, CA/Bangaldesh India (he's back and forth).
Combined Programming Language/Framework exp: Rails 4.0, Ruby 2.0, JavaScript, JQuery, CSS3, HTML5, AJAX, Vast understanding of web architecture (http, TCP/IP etc...)
The work itself is quite advanced compared to other projects I've worked on. I feel a bit strange boosting the hourly rate up double but the reality is, taking a project like this on fulltime I need to make sure that my needs are met/covered.
