Email Extractor -Monster,HotJobs,CareerBuilder

I need to extract email addresses from [login to view URL], [login to view URL], CareerBuilder.com. Since there are millions of jobs on these sites I need a manageable way to extract this information (i.e. could be posted date, category etc - you recommend). The software should be user friendly and easily deployable to Windows XP. I need to have filters (i.e. don't collect or %@[login to view URL]). I want it to be highly configurable preferably by text file, in case any of these sites make changes I should be able to make configuration changes to adapt to them. When you bid make sure to answer the following questions, do NOT paste a pre-written message. 1) On what basis do you plan to collect the email addresses? (By date, category, etc) 1) What technology do you plan to implement this with? 2) Describe the architecture design 3) Do you have any other helpful features in mind? 4) How do you plan to implement filters?
