Hi,
I would aim for 120 depending on how receptive they were when i got there, i would be prepared to do the job inc re sanding for 90-100 if it was close, i was quiet, and they booked it with me there and then.
Also factor in the cost of gettting work from your ads, if i can quote a job a little cheaper and secure it i will often get more full price work from it off the neighbours.
i am in northwest and prices vary throughout the country, might help people if we start to indicate what part of the country we are in when giving our estimates?
steve
P.s i wouldnt expect to spend more than 2.5 hours in total inc re-sand on this
