I do one place, the money until very recently was excellent, an hourly rate of about 3 times what a lot aim for on here.
When I took it on I acquired it from another shiner, I was able to basically double his price, through some careful engineering of what we negotiated at the time; but now they have a new area manager and it seems most services have an allocated budget; whereby Ive had to take a cut in my earnings with them but they dont get so much done. It still works out at about the same hourly rate, just they dont get their windows done so often.
Price was initially worked out at a price per window and mulitplied up, but the fortunate thing was there were no ground floor windows, so its a piece of cake.
