What would you do?

So long story short and I don’t want to get into the details due to privacy but I can get my hands on about 500lbs of sorted brass a year for basically free. Mostly 9 mm but decent quantities of 40, 45, 223, 38 and 10 as well. I think I am going to start collecting it as I have the space. But my question is what would you guys do? I’m a freak and I love cleaning the brass, counting, sorting etc… and also reload for myself some but not near to the volume I can get. I would like to retire in the next 10 years so I figure I start saving it now I could have quite the pile of brass and as a part time job/hobby clean, sort, and sell the brass.

What are your thoughts on this idea? I figure if it gets old I can always just say “fuck it” and scrap it and I’m still only ahead in the deal.
