Hi,
I also work two or three days per week to other commitments and find that since moving over to WFP my earnings ahve gone up. As I only had aenough work to fill 2 days per week using ladders it's taken a while to build up more now that I am quicker with a WFP.
I also found that I could take on work I wouldn't dream of doing with a ladder (too high, too awkward) and I can charge a "healthy" sum to do it with my WFP.
I am now trying to ween out from my round the houses that are too cheap, and replace them with the high paying house, 3 storey houses, large coutry properties, awkward to reach windows ect, so I can make my WFP pay better.
i also got the feeling when I first switched that on some places I was cleaning them too quickly for the price I was charging but I view it this way:
I invested £xxx in the WFP for my benefit (safer/quicker ect), not the customers benefit. We agreed a price for the job, not for the time spent. As long as they are happy with the job that's what counts.
If you are really worried about a customer complaining that you ahve been "too quick" jsut aim to clean it when they are not there!!!
Cheers
Steve
