Find Script Injections

Basic Requirment I am looking to develop a program that will scan multiple websites (just the index pages) for injected scripts. I need to be able to enter the websites into the program easily. I would provide text of these scripts and would like to be able to add new scripts in the future and scan for those as well. I would like a report in xls as to whether the scanned websites were found to have code matching that or similar to that of the scripts provided. I would like this to run on a chron and mail the report to me. Add on: I would like people to submit their site to this list and then be able to download an a graphic indicating their site is free of malicious scripts (as long as their site is free of the scripts in the library) the icon would be green as long as it is. Bids Please bid for both the basic requirement and the addon separately.
