Email to Lead Scraping

We are just starting with SalesForce and need our email inquiries to flow into SF. Those emails are email inquiries that we need to auto-scrape into a lead form. There are email apps out there, but they all create the lead based upon the Sender. For us, the sender is usually the advertising channel and the lead data sits in the BODY of the email. Therefore, we need a script that runs through incoming email and that can scrape the data from the body of different email sources.
