Turkish Rug Appraisal

Need suggestions on a good place to get an appraisal on some Turkish rugs.

My parents recently returned from a trip to Turkey where they purchased a few rugs. Need to get an appraisal for insurance purposes. Also to see if they did okay or got ripped off.

Googled and found a few places that will do an appraisal.

I wanted to post here for recommendations on where to go based on personal experience with getting an appraisal here and Houston.
