Hi thats what i set up early this year, as a weekend job, was great to begin with, i got plenty of saturday jobs out of it, and yes an extra 200 pound on top of my wages was great..... then i walked away from sales, but thought oh well i will really go to town..
on the pressure washing side...
i have two industrial petrol machines, all the turbo lances etc,.... then it dried up,
you need contracts with places like nursing homes , tennis courts, burger king, grafitti removal, with the council and places like that to really keep going,... you can also buy attachments for drain unblocking....
i decided to try and build a window cleaning round and if i see an overgrown driveway, i drop a pressure washing leaflet also.
its paid for both machines and a van, but just doing driveways is not enough, as its only in spring early summer that its steady.
gary
