Betfair datamining / data scraping project

Hi, I am looking for someone to write a programme, preferably in perl, that will datamine certain data from betfair.com. I would like every single market under the 'baseball --> mlb 2010' datamined on a regular basis. For example, for individual matches, every hour up until 2 hours before the match starts, and then every second from then until the end of the match. For the non fixture markets (such as american league winner) I would like the market datamined every hour. I want every back and lay price available, as well as the amount available at that price, and the date/time the data scrape was made, in an easy to manipulate format (such as .csv). I have an active betfair account. I am looking for someone specifically with prior history of writing a betfair datamining programme, and someone for who speaks very strong english. Price is negotiable, I'm not sure how long this will take and I will listen to offers. I can email more details upon request. Thanks!
