Dear Sir or Madam,
If your input data is already consistently formatted, then making the proposed edits/cleaning will be a simple task. I should be able to complete your task in one day, but have quoted two in case there are issues.
If you can send me a sample spreadsheet, then I can give you a better time estimate. But, if it's the task is as straight-forward as it sounds, I will just finish it and return a sample for review. I can start as soon as I have the spreadsheet(s).
Thank you, for your consideration.
Allen Heaton
p.s.--I have updated my quote, as I have adjusted for the Freelancer.com fee of $5.
