Website Content Scraper

I'd like the contents of a website to be scraped for me please. The website is http://www.oddsmonkey.com/OddsSearch.aspx

Notice the drop down menu to select 'bookmaker'. I need the script to select each bookmaker in turn and then use the filtering options in the 'back' column and 'available' column. The filtering values for each bookmaker are different.

After the results are returned, the first page of results for each bookmaker need to be scraped and collected into a CSV database which will then be saved where I have hosting.

This process needs to be automated and repeated multiple times a day.

I have a lot more detail and a full spec for anyone interested.
