Data entry for a small company

I am in need of an experienced data entry contractor to enter data into spreadsheets for my small business. I have a basic concept of what format I would like the data to be entered into, but don’t have a specific template. The data entry task requires the contractor to enter more than 500 data points. Accuracy and attention to detail are important, so I am looking for someone with excellent organizational skills and who can work quickly and diligently.
