Houston appraiser (art, silver, jewelry)? Estate sales? Declutter help? Donation orgs that pick up? Menswear consignment shops or online resellers?

Inheriting a bunch of stuff I don't need and would rather liquidate by end of this year.

Many thanks in advance for recommendations for:

Estate sales firm(s) that can host estate sales elsewhere (HOA won't allow an estate sale on-site where the stuff is located)
Appraisers – jewelry, antique silver, and art
Declutter help that's reasonably priced and efficient
Best men's clothing consignment shops and/or reputable local online resellers
Orgs that can pick up donated items (not larger ones like Goodwill, please)
