I've been doing this for friends for their thesis writing for over a semester now, and the fact that I can type accurately without having to look at either the keyboard or the monitor makes this a breeze, and i can possibly multitask while doing it. If it isn't satisfactory, I'm ok with not being paid for it, but don't worry, it won't be.
I charge INR 5000 for 50 JPEGS, and will be able to complete 50 every two days, so depending on how many JPEGs you have, I can tell you exactly how much I'll need.
