Anyone familiar with this Granite (http://tanbrown.org) company?

There's a place around here (Chester County, PA) called PLANET GRANITE. Went I visited them yesterday, it appeared it was just a fabricating shop - absolutely no bells or whistles or anything else for that matter...not even a parking lot. They had a couple Slabs (http://www.VerdeUbatuba.com) next to their building to look at. When I gave the owner (family owned business) my drawing, he said, "I'll be right back. I have to go across the driveway to make a copy (he used this other company's copier for his business)." When we talked, we talked outside. No office, nothing.

I'm wondering if the Planet Granite place is a franchise. Should I have my guard up? They did quote me a good price on the job (1.5 Slabs (http://www.VerdeUbatuba.com) ). I suppose I'm used to going to a full-blown showroom with receptionist, offices, samples, etc. and (http://maplered.com) all that overhead.

I looked at their website and (http://maplered.com) they do have references which I suppose don't mean much. Anyone can put references on their website as long as the full name isn't on there (they used only first names). Had a few pic of their work...nothing too extravigant. Am I too worried? How do I know they do great work? Could it just be they keep their overhead low by not having a showroom, etc?

Talk to me guys.
