I did the same thing when i started ,

I had no customers at all , the first summer was a killer , i worked until 7.30 every day and all of me ached , but i was full up within 2 months , it took a while to get the gutter cleans done , but this i explained to the custys ,they were all cool about it but did remind me not to forget i owed them a gutter clean !
I would say i still have all the customers bar the ones that have moved or pegged it.
Was i MAD ........ I dont think so , it built the round in no time , and i was still on ladders back then .
