Create Help Documentation for Windows Application

I am looking for someone with experience writing application help text. I have a new windows application that is almost ready to be released but I need someone to create some of the help documentation. The windows application is a data quality software package. The person selected for this project will be provided a copy of the product and be required to build a help document describing how to use the various features of the tool. Because I have a limited amount of money for this project I do not expect all the documentation to be written just some of the key features of the product such as Importing files, profiling file, JOINING columns, Splitting Columns and cleaning options. I will also provide a lot of technical writing on each of these features. I would prefer this document to be developed in an HTML editor like Dreamweaver since all the help documents will need to be setup as HTML files. The person selected must have experience writing application help text and have a good command of the English language.
