hi dave.
it sounds great,
if you have a team of 4, then i would think it will take you at least 3 days, but price for 4 days just incase,
then i would charge £14 per person per hour, take about 6hrs a day, = 24 hrs.
then pay your cleaners £6 per hr
so i would think a price in the region of £1344.00
£144 to pay the cleaners.
£100 for the material,
and the rest is yours
if this sounds expensive try £1000, and your still quids in
thanx jonny
you wouldnt be far off.
