im with Mike on the time scale, 2 weekends. As for price you could charge it 1 of 4 ways. what would you have to charge to make a good profit & to cover expenses;
a, per sqm
b, per hour
c, per day
d, per job
I have just worked a price out in 2 ways and come up with pretty much same price for both (sqm & hourly) so i would charge between £4500 - £5000.
