Send it back if you can. For that price I'd expect a factory set up to have no problems.
Is your luthier buddy a luthier or someone who just does set ups? Either way really, it shouldn't take someone with experience and knowledge to diagnose the potential problem, and tell you what's wrong in a short period of time.
I've become very wary of people who've been in bands, tweaked their own guitar a couple of times, then all of a sudden they're calling themselves a luthier. I used a guy once who told me the neck on my Korean Squier was made if 'rubbery maple' and that's why the action would always be a problem. He was talking drivel. I did the set up myself after he had been at it, it was fine. Now anything I can't do I take to a guy who makes acoustic and electric guitars, an actual luthier (the lead singer in the Manics uses one of acoustics)
