Article Rewriting wordsmithing content generation

I am looking for a good technical writer, wordsmither and article content writer. Preferably with medical background and am familiar with medical terminology or medical products. You will be given a spreadsheet with at least 4 columns containing text from various locations from web and book references approx 100 to 300 words each in each column that describes a specific category or product. You will be required to take parts of the writable content from any and all the columns and generate a unique category or product description that can be used as descriptive page text or introductory page text. You will also be required to gather (cut and paste) similar text from different web sources. if it is not on the sheet I give you. You may need to add that to the existing excel sheet or make a new one. The final text should comprise approx 100 to 400 words per category per page. I'm looking for the text to reflect the page contents for SEO and it needs descriptive keywords which will be found on the different sources of similar text that are in the spreadsheet. It will be up to you to make sure at least the category or product name is mentioned 3 or more times in the introductory text. It needs to be included in a natural manner and not just place as keyword stuffing or repeated excessively. The page descriptive text will be required in two different paragraphs. The first part of the text is the introductory text and will explain what is on the category and product page, approximately 200 words. The second part of the page text refers to how the item can be helpful or it's benefits. I can explain more later. The resultant text you develop will first be used to clarify and describe what category or product information is on the web page. Later it may be used with additional text and provide the basis for articles relating to the products or similar categories it describes. It needs to be written for US readers and flow naturally. The person will submit a 60 or more word article about any medical product they pick so I know they can write and not just respond to this post. The paragraph text must past copyscape and be original. You are bidding on an hourly basis. I currently don't have the excel sheet with information but am working on it. The first part of this job will be to go the the sites I specify and gather the information (cut and paste). Once the column information is gathered then the wordsmithing can start. This job will be at least 40 hours if not more and report is expected daily. If results are not shown. You will not get paid. I will not pay someone no matter how low they bid for not doing the work.
