"800 got junk" is a 20 year old franchise operation using more or less the business model above with hundreds of franchise locations.
A 150 year old non-profit with a nearly identical business model is the Salvation Army, although they only do donations and don't pay for junk other than kind of optimistic tax donation forms. They do have the model down WRT truck rolls up to house and junk disappears to be sold at a resale store, however no money officially changes hands at junk acquisition time.
There are also innumerable decade or so old ebay resale operations which frankly are shoveling junk. Yes I'm sure there are some, but not many, specializing in "non-junk".
