Selling off entire inventory of heat transfers

We started our business by using ready made heat press prints but have now focused more on custom items.

I do have 2-3 thousand prints left that I would like to sell... There are some higher end prints like Liquid Blue ones (about 3-400 of them) as well as some basic text ones.. a huge variety that is pretty much impossible to list.

I would like to sell as a lot to
1. Liquidate these assets
2. Create Room
3. Will probably never use these and do not want them going bad/dry over time

`Any ideas, suggestions or best of all... offers?
