Data Entry in Excel/Spreadsheet - Need Organized Person

We are looking for someone to enter data from one spreadsheet to another. There are 670 columns and each column will need an average of 10 entries. We will provide the data (use side-by-side viewing to copy and paste). This is easy work for someone familiar with excel. Accuracy is very important especially in two cells that have prices. Only one cell in each column will require that you get the info (company name) online and we will give you the source. This task requires someone who is organized and trustworthy as we might not be able to go through all the entries immediately until we upload on our site. We will therefore leave feedback for the work after one month to allow any errors to be checked but will pay as soon as work is done. There is potential for re-hire if we are happy. The work needs to be done fairly quickly. Reasonable bidding please! We recommend that you estimate how much you want to earn per column to get an idea. Thanks!
