Are there any trustworthy gunshops in Hampton Roads Va?

I inherited a bunch of guns from my grandpa. I found out some of the shotguns i got are worth a lot of money. I need help from a trustworthy gunshop to ID and value the guns I don't know what they are. I called bobs gunshop in norfolk to ask about it, all they seam to want to do is buy them and not aprase them. I also need help checking them to see if there loaded ornot, some of them were and arent now, some I dont know how to open them so Im not messin with them. Can you tell me about a good gunshop, or even a gun smith that will help me and be honest and not try to buy grandpas guns for pennys like bobs did.
