Did you look at the feedback on his profile already left by some trusted members?

Look at the advertisement thread itself. It's self moderated with so many posts from different users already deleted. It's a scam tactic. That alone should have been enough to alert you.
The OP is a newbie, so maybe he didn't do any research before dealing with that person.
Checking the feedback alone will make you hesitant to have business with him.
This is a learning experience for the OP, check the background of the person first before making any transaction.
