Hi there,
Your project looks pretty straightforward, but I do have a couple of questions:
1. Based on your selection of javascript as a category, and the github project you referenced, it looks like you're expecting a nodeJS app, is that correct? The other option would be an HTML page that you open locally, which could use the HTML5 FileReader API to read the data and generate the results for you in a browser. Either method is fine for me. If you already have nodeJS up and running, that's probably a little easier from my point of view.
2. Can you tell me about the structure of your CSV? I'm guessing it just contains lat/lon pairs, and you'd like an additional column added for country.
Neither of the above affect my bid, but I'll need to know them before I can get started. Once you accept my bid and create the milestone, I think you can expect the result in under 24 hours. Depending on the time of day locally, I can probably have it for you within a few hours of acceptance.
Thanks much for considering my bid, and please let me know if you have any questions.
