Collect previous years exam question papers

I need a collection question papers from various entrance exams in India. The collection should include all the biggest engineering, medical, law, and management entrance exams in India from the last 6 years. I am looking for at least 500-1000 question papers - more the better. The papers will need to be renamed according to a file naming convention I will provide. When you bid please include the number of papers you can collect. BTW - The files should not have any watermark or copyright inserted by other web sites, and should be clean copies of the question paper. So, before you bid please do a quick search online, message boards etc and make sure you can deliver the quantity I have in mind.
