Php Developer with a decent JQuery knowledge

I need a Php developer to work on a quick project.
I will need you to create 10 - 20 classes. These classes will conform to certain rules and will be required to produce obviously certain results.

Only apply if you have a very good understanding of php. Don't apply if you don't have good experience otherwise your bid will be rejected even before I read it.

Additionally, have you worked on Backbone before? If you have, show me an example of your past project.
