Web Programmer - website scraping

I need a full-time PHP programmer. The applicant should be a capable developer, but does not need to be an expert.

The project involves scraping webpages of online retailers and extracting information from those websites. I have a large list of retailers that need scraping. Each vendor takes me 1-4 hours to write a parser for.

Website scraping will use either regular expressions or Simple HTML DOM Parser, unless applicant has a preferred method to scrape websites

Other duties may include fixing old parsers which break, general code maintenance and smaller projects that I would like to get done (both frontend and backend)
