Any tips for where I can sell my collection as a whole?

I'm not ready to post photos or share the list yet (still sorting) but I'm trying to get an idea if there are any good places to sell entire collections. My sets are either used sorted into bags like the original instructions (bag 1, 2, 3, and so on) with instructions (no box) or NIB. When I'm ready to sell, I'll have a Google Sheet list showing every set number, name, and the status of the set (used vs NIB). Any tips?
