web data extraction

a website publishes the email addresses of its newest users on its homepage. The page is dynamic, so the previous data is replaced when a new user joins the site. I need a system to collect all the email addresses displayed on his site. Right now, on an average,the page gets new email every 10 minutes or more. At the end of a day, if the site has 50 new members, the email address of the last member will be showed at that time. But I want a system to monitor the site all day so that I get the other 49 addresses as well. I want a complete solution. It can be as simple as a web user sitting all day refreshing his browser to get me the addresses. Or it can be a software crawling the site every 10 minutes to retrieve the addresses. A cheap server solution to run that software will be also welcome. Please respond as soon as possible. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
