Reselling ~2000 comics?

I won a storage unit auction recently, and there ended up being around 2000 comics in it. I mainly resell the stuff from auctions I win. Wasn’t really expecting such a massive amount of comics. They appear to have been from someone collecting them, as they all appear to be mint or near mint, in their original sleeves or whatever they are called, unread I’m guessing, and seem to be of late 90s timeframe up until late 2010’s. I’ve been using Comic Book Realm website to price them and started an excel spreadsheet for them. I’ve gone through about 15% and the value from that site is sitting just shy of $2,000. I’m wondering what I should do with all of these, after cataloging all of them. Any help would be appreciated. Thank you.
