Ruby on Rails developer to debug/update existing site

Ruby on Rails developer needed to perform bug fixes and enhancements to an existing site. The site is currently running on Rails 2.3.4, employs Haml for some view rendering, and Rspec for test coverage. The site is currently deployed under Passenger on a shared host. To start I need 2-4 hours of debugging and small updates. More details to the chosen provider. Please provide live links to sites you have built/administer. thank you.
