Developer that can work with Freelancer.com API?

I am looking for a programmer who can work with the Freelancer API and Facebook API to help me test out a new marketing idea. I would like to use the APIs to put a keyword filtered list of projects up as either an App or a feed on Facebook and Twitter. What I need in its most basic form is a solution which takes the Freelancer Project feed and filters it to create a new RSS feed of projects which contain a particular keyword, i.e London, Manchester, Bradford, Leeds, etc.. and then these jobs can be automatically posted to the Wall on our UK Facebook Page, or better still under a new "UK Jobs" tab on our Facebook page. Would be good if the same RSS feed could be used to auto-post to a Twitter Account for Freelancer UK Projects.. Any questions please ask me..
