The company is actually called DUSTLESS BLASTING. if you google it should come up ( U-TUBE). its a turn key business. Similar to a franchise but without the added monthly compensation franchise fees. There are different packages. I think the only catch, is that you have to purchase their media..(it seems)
I looked into this a few years ago but the upfront cost was a lot more than I was willing to invest, plus there are more than a few sandblasting operators in this area already. Market saturation is not far off IMO.
