Not sure where to start so here goes. Started window cleaning about 2 years ago and its took off better than I ever expected . If pays a very good wage for the hours I do. Up until 2 weeks ago I had a customer base of approximately 270 customers that I cover over a 4 week period. My son is now coming on board in 4 weeks time as he’s fed up with his job so I’m going all out advertising , I’ve managed around 30 new customers in the past fortnight . Just worried I’m not going to be able to build up the customer base required to pay 2 wages. But how else do you expand.. I’m considering going down the route of offering gutter cleaning and pressure washing. Your thoughts please ?
