There must be some sort of benchmark written down somewhere, but where it could be say, £0.60p per sq.ft in your town, in a small town 40 miles away it could be £0.30p per sq.ft, or in a city 10 miles away you could get away with £1.00 per sq.ft!! Do you see what i mean. In a lot of posts recently, a couple of us have said that when we began business, it was a "suck it 'n' see" response to how much to charge....after around 5 or 6 quotes, you begin to realise what you can charge.
How do you purchase training.....and what is that to do with the cost of cleaning per meter/foot?
