Art Hanging Services? (Cary: area, reviews, company)

[hertfordshire]

Does anyone know of any art hanging services in the area (specifically Cary), or should I just go with a handyman?

I want to hang 6 large frames, and it's going to require pretty precise measuring to get them all to line up properly, as well as probably a 10' ladder. A quick google gave me one company that appears to be a local franchise of a national company, and I can't seem to find any reviews. Anyone have any first-hand experience with hiring someone to hang art?
