I'm not too keen on the big jobs Matt. I think your rates are better than mine, but as in your day rate thread, not many are happy with 400pd.Our business is based on working for a lot of customers for about twenty minutes, or ten even, and charging small amounts that give a good hourly rate.Hopefully they never reflect too much on the bigger picture.
I'm guessing but i bet the handy man will have two hard and cold days doing what you do in about three hours, good luck to him, but the guvnor obviously thinks if you can do it maybe a live in polish polish person would work a fortnight for that money.
If this colonel type ever meets you in the pub and tells you as much, say yes, but i gave you a good caning for a while old boy.
