you want to earn *£50* an hour, when you get your kit and have some training then practice on your own and friends carpets. time your self and then deduct 20% of the time as you will get quicker within a couple of months
from this you can work out how much to charge to make £50 an hour
eg: in an hour you cleaned your through lounge add 30mins because with a real customer you will have to travel to the job..... so you need to factor in that amount of time, so that through lounge took an hour and a half (approx) so charge £75
this is a simple way to work out your price, the amount per hour you want to earn is a personal thing
