Convert Facebook UID to Email with API2.0

As in title, I need Facebook converter that will convert Facebook UIDs into emails with Facebook API 2.0. Yes, it is possible, but there's some way around to do it. Currently very popular software called 'Social Lead Freak' (SLF) does it without any problems. I know that this process requires checking UIDs one by one, there's no bulk action possible to my knowledge. In SLF software, the converter does it one by one. Don't worry about graphic layout, I don't care about it. What I need is functionality: a script that converts UIDs into Emails, that's it. Output in any format is acceptable, either it's file to download, list of emails shown in the same textarea or new textarea, whichever is easier, any will do as long as 100% (or close to 100%) uids are converted successfully into emails. How I think it would work (it's just my idea, I'm not really sure how SLF works): - script finds Facebook username based on UID - then adds '[at][login to view URL]' at the end of username (sorry, Freelancer.com doesn't allow to use 'at' symbol, so by [at] I mean actual symbol) second point is obviously easy, the problems starts with first point (how to convert uid into username); But maybe it's possible to convert UID directly into email, I don't know, that's why I'm posting this project ;) I would be more than happy if you can do it for around $100-150, however, don't hesitate to post any other price, I will consider all offers. Please bid on this project only if you know that you can do it according the requirements and if you can do it at all. Again: don't bother about graphic layout at all, focus on functionality only. Also, please comment your source code (just important points, don't worry about it too much either).
