An Experienced Internet Marketing Writer

Hi, I'm looking for an affordable but excellent writer with very good experience internet marketing to writing E-books. This includes topics like Making Money Tactics, SEO, PPC, CPA, Viral Marketing, Traffic Generations, etc. I will be providing products/material for you to pull research and material from when needed. I will still expect you to be able to create a unique system on your own. The E-books should be roughly 400-500 words in length per page and usually 20-30 pages each with unique content. They should be well researched. Each E-book must be all copyscape proof, cannot be plagiarized, and cannot be generated from spun content. All work will be checked and you must agree to NDA. I'm also looking for people who can provide this at an affordable budget, though this will definitely be long-term work if you can pull that off as long as you can provide quality. Please provide samples or a portfolio of your previous work and experience when you bid. Thank you.
