Sell something for me

I am about to finish a novel and although I could probably learn how to convert it for publishing I am planning on completing more books in the future and would like someone to deal with this area. In addition and more importantly I do not have a clue about on line marketing. Please contact me if you are able to either or both. This is only the first of many projects required. In addition to initial fees I would also like to include a % of sales.
