Part-part-part time job

Well, I might have a small part-time job. I'm editing text written by non-native English speakers. The files are sent to me over the Internet, I edit them, and send the edited version back. The job is really easy for me (except when I'm not quite sure what the person meant). They're paying $28 a day so far (depending on the amount of text I edited). I'm a little worried that this might be a scam, but I guess I'll find out one way or another. One thing's for sure: I'm NOT giving them my bank account number to pay direct deposit.

Edit: Quoth the person with whom I'm working, "You do your job really good." Ah, praise, the wonder drug....
