Need a crawler/grabber that will
1. search up to 20 user-specified websites and social networks for user-defined keywords and friends' data (using authorized member’s access to friends’ data), and
2. store results in database table.

Well I have already made something like this in Java about 4 - 6 months ago. It just doesn't yet store the results in a DB but I know that should be easy to implement. I don't really know how long it will take. I just estimated it to be 30 days. It may be more or less depending on your requirements.
