28 page book research+content addition start ASAP

I need a 28 page ebook to be rewritten 1) some areas needed to be researched more and pictures added to to make the book more complete but, the bulk of the content 60% is already done, I just want you to do more research and include more content as I feel it is not good enough. Looking for a fast finish I'm looking for someone who would be interested to work longterm with me and is sick of working several different projects at once and doesn't want to deal with the frustrations of having to deal with different people every time and who may be interested in getting a lumpsum of the profits for several projects that I have going on that all have marketing plans and proven hungry buying markets. I'm looking for quality work and not a rush job! Something who can work quickly and efficiently. Please reply with when you can start and how low it will take for you to finish the project. Please send a sample work.. Job starts right away.
