I have a lot of experience matching data between two sources. I recently worked for a company where I did this on a regular basis, matching data hundreds or thousands of rows at a time. I was able to automate a large part of the process with formulas, etc, but sometimes a simple period threw off the matching. Like what you said in your project description, sometimes data is entered in different formats. I have the exact experience needed to match data of different formats.
As you requested, I am incredibly attentive to detail and have an eye for consistency, as well.
You've requested that this be an hourly-paid project. I've submitted an approximate bid, but not in hourly format (as freelancer wouldn't allow it). I'd love to talk with you further regarding your budget and how I can help you accomplish this project.
Sincerely,
Andy
