Who owns a commercial pressure washing business?

I want to start my own commercial pressure washing business. There's no money in residential. Does anybody think this is a good idea?

Have you any contacts, are there lots of businesses with commercial vehicles that need cleaning or industrial equipment needs cleaning, in your area?

It is a good idea if you can make it work.

Buy your equipment 2nd hand, but is good condition.  

Look at mounting it on a small van or pickup with a water butt (In UK this would be 1mtre cube holding 1,000 litres or IBC Intermediate Bulk Container)

Good idea try sounding out some haulage companies, if they already have a person goes in, how often do they go clean?  How much do they charge?
