I'd probably look at current listings AND completed listings to get a feel for what other sellers are doing.

You don't want to make too much work for yourself if the lots/packs are of lower value.

As for storage: what about buying a pack of those clear plastic pages and a 3 ringed binder. I keep

some of my collectables like that (trading cards and other ephemera). Easier to view/access than

files and boxes!

I don't know if there is a way to streamline the photos process. Maybe just set aside some time

and just do them one pack after another, maybe a couple photos of each (1 of the bundle and

another with a few of them spread out), neutral background and some good light. Good luck.
