Conversion of Documentation to a WIKI

We have a collection of 50-60 pdf/doc/txt/html/xls documents with images and diagrams. Documents range from 1 page to 40. We need these documents converted directly into our wiki. If diagrams are in documents, I need the images created and uploaded. XLS -> html tables, pdf/doc/txt/html -> simple wiki entries. Each of the documents needs to be broken down in to useable entrie sizes which do not contain more than one topic. We do have a documentation standard and a few documents as examples. This is NOT just a copy/paste job; organization of the documentation is going to be required as well. Previous experience with technical documentation and wikis is a must. Requires a native English speaker obviously. I will not pay a deposit, but I will do partial payments as the project progresses by 35%, 35%, 30% completion.
