These Commercial Laundry Machines have my brain working

[Colby Easterling]

So, this  property came with a whole lot of goodies, but this was just one other thing. We are considering selling the machines because we plan on using the store front for other things. 

(quick run down of property: 3 lots: 2 SF houses, 1 Store front, 1 empty lot for 15 grand cash. Can post more about it if you're interested)

Anyways, although we may sell them, I have had brief convos with my wife about coin laundry and card laundry and she likes the idea. Now that I, by chance, own some. My mind is racing with the opportunity of opening the first local "card laundry" around my are. Told one of my buddies that lives in another state, he said if I decide to jump on the idea he will join me. 

So my question: does anyone have any experience with coin/card laundry? And I can't find card laundry machines for sale to feed my interest. Anything will help, I'd love to pick your brain, thanks!
