I can lend you my programming skills as a M.A. in Computer Science and experienced database programmer (mySQL/PHP). I can implement your URL scraper quickly. As for details, do you need a link crawler or just the traversing of a giving list (store/x with x>0)?
My solution will be rigorously documented and tested so it will be extensible as well as robust.
As a flexible freelancer I won't have problems meeting the deadline.
Kind regards,
Kamiel Verwer M.Sc.
