Convert a Firefox add-on to a Chrome extension

I've developed a Firefox add-on that's about 700 lines of javascript. I need it converted to a Chrome extension and *thoroughly* tested to work perfectly well. To bid on this project please include answers to all of the following in your bid comments: 1. what experience do you have with Firefox add-ons? 2. what experience do you have with Chrome extensions? 3. what experience do you have in Python? (I've also developed a Python script to assist with testing the extension) 4. what experience do you have with Ruby? 5. how much time do you estimate you will need to complete the conversion?
