So we get a warning that a member here has gained $3500 from you with this, yet no one has a clue who it might be? 
With that note, I wouldn't want to hire ANYONE to do anything.  Who knows who it could be.  You could possibly hamper opportunities quite a bit of developers who do private work, by being so vague.  We now have 2 major complaints about money being doled out to developers with no product in site, to the tune of $5500+.  At least one is known.
Unless their is some kind of proof of payment, this is hard to believe.  I'd be getting my money back, by any means necessary. 
I am hoping many of the developers I trust and have purchased items from can now clear there name somehow.
