Combine 3 Ebooks + Add + Sales Letter Re-write

I need 3 of my copywritten ebooks combined and copy added to make into whole larger ebook. Current copy is about 100 pages. Want entry-level copy to be added regarding on how Ebay works, selling tips, etc. You can get this from any book out there on the market and re-write, as they are ALL the same. Need 100 additional pages of this. Need index made of book content. Need sales letter to be re-written and added. Thanks, and I look forward to working with the winner!
