In general window cleaners who are just starting up are wasting their time canvassing to get a couple of houses here and there then come on here moaning there fed up of getting in and out of their cars all day...all of this can be avoided by purchasing a round... at the end of the day you are only investing in yourself,this investment will never go down, provided you clean to a decent standard. So put up the cash hit and hit the ground running don,t lose days due to no work etc.....then by all means do the canvassing later and see if you would take on one house here and one there .. i think not..... rant over
