thing is jim none of us work 40 hours a week "on the glass" more like 6 of 7 hours a day.we dont get paid holiday/sick pay.when the weather is really bad,again we dont get paid for downtime.then theres tax,insurances,expenses of running a van/car,accountants fees,equipment costs.albeit if your trad you wont have too spend much on equipment year on year.
seriously if i was only making £16 for 75 mins of work on a posh restaurant id of dumped it by now as i can make better money on cheap compact 3 bed semis.dont forget you have to drive to your next job so thats another 5-10 mins eaten into that price you ve charged for the job.
min price per hour worked is £25-£30 for me.although i have some work where im making £50-£60 an hour "on the glass" time but not hour after hour,day after day.
at the end of the year when all expenses and tax are taken off its not as much as you think!!im still doing well,in fact better than ever after years in this game but to be quite frank jim you will make next to nothing and just about scrape by with the prices your charging for the job.
best wishes
