for anyone who would like to get into huge ccu's or more jobs. what i would reccomend is call some local post construction cleaning companys and find out if they need a window cleaning company to use for window cleaning.
in my local area there is a new company that is owned and operated by two ladies. they do huge jobs and use me for their window cleaning portion of the job. i get my price and they make it very clear to their builders that they sub-contract the window cleaning out. builders are fine as long as the job gets done and the end result is good! im telling you this one tip i learned on my own. and it has paid my thousands of additional revenue! my only issue is that i need more help in order to get the jobs done and still be able to take care of my growing residential customer base!
