Hi all im after some advice please i have been asked by my window cleaning customers if I do power washing drive ways etc . Always one to expand my business im looking into it .
1 should I use a petrol machine
2 do you use your own water or the customers outside tap
3 do you price per hour or price per square metre
i have been looking at a pro user 5.5 hp petrol washer are these any good for starters
many thanks Gavin
