No offense squeaky mate, but seriously are you having a laff?
How can you NOT earn £150 a day with WFP?
I know I can be sarcy etc, but i'm being serious now. £150 is what most WFPers would manage standing on their head. Matey, you seriously need to either raise your prices or do something to get faster.
And as for bills yes yes, but window cleaning gear is not a bill. If a knackered pump stops you earning money then it will cost you much more in lost work than the cost of a new one surely? Honestly I am not having a go now, I am serious.
