Continuous Data Scraping with an Admin Interface

My team and I are looking to continuously pull structured data from a few sources, 11 sites to be exact. Some of which are directories, others are review databases, and 3 of which are Social Networking sites like facebook & Foursquare. We are looking for someone to help us conduct a; [login to view URL] time scrap of sites [login to view URL] scrapping to identify and retrieve new information [login to view URL] information across multiple sources [login to view URL] when scripts fail or produce errors eg site goes down, blocks IP or data structure changes We'll send across more details if you are interested and have the time to take on the work. We are looking at a pretty short time frame though of 1-2 weeks.
