Persian Rug Appraisal Inquiry

Hi Friends, I have some really fine, high-end, hand-knotted Persian rugs and rug runners that I’m going to sell to raise funds for our family’s upcoming move on May 31 and for my salary as I work full-time in widow ministry. Any suggestions as to where I may go to get my rugs appraised and any idea where I may sell these to get a good return? As I look at comparables online, they are worth a significant amount.
