Hi, I have extensive experience in pdf to ebook conversion and would be perfect for your gig.
What you need is a valid 3.0 epub for the iPad and a mobi file for Amazon. I've done dozens of these conversions and would be happy to send you example work.
I have all of the necessary software (acrobat pro, Calibre, ect...) and am more than willing to do revisions if you find any errors in the conversion.
