Sorry, if this was all for one customer on ame job, I'd probably do it for £325 - £350
I charge £180 per day or £25 per hour! It could be done in a day, but would ccertainly charge more than a days rate. Oh and I also stick 20% on parts.
Interested in why you would charge more than a day if it takes a day?
Well, a days rate sounds too cheap, I don't really like charging a day rate as I feel I do better the other way., see what I mean, I'm not the best at pricing jobs.
