PDF Data Transfer to Spreadsheet

I'm looking for an accurate and diligent freelancer to extract data from a scanned PDF document and enter it into a spreadsheet. The documents consist of 50 to 100 pages, each of which contains data in a table format. This project will require a careful eye for detail and experience with both Microsoft Excel and data entry from a pdf file. Typing accuracy and the ability to maintain data integrity are important skills for this task. There can not be any errors. Please provide examples of similar data entry projects that you have completed in the past.
