Hi
for those with full schedules why not take some one on or find a good subbie to do these jobs.
at 2 and 3 times normal rates you could pay them top money and still make great money for yourself for five minutes on the phone.
i have a factory its every other year!!! but they get me in when they cant see daylight anymore. its great because they arent going to come properly clean,they arent expecting it to. they just want the thick off to see again. it rinses straight off. one of my best hourly rates, because i charge a fortune for it but they arent bothered because its only once in awhile. and they arent going to complain becuse the improvement is dramatic.
i wish i had 500 jobs like them, just trip round in a two year cycle one a day. would be minted and stress free.
i think ians figure of 3 times is spot on allows for any disruption and travelling plus dig out time.
cheers
john
