Don't know why any1 should worry about the claims on any of these sites - in general it's close to what you should
expect to be turning over per year - thats not your wage/income
as also mentioned you just don't start out and get that sort of turnover ! it takes time and by then most new starters have got hacked off and given up!
As for commercial work - yes hourly ratres can be double the domestic rate, however (for me) these are independant companies that want a quality service not a wash over for a couple of quid.
weather you can find enough 'premium' jobs to earn £70k per year is doubtful. and with contracts all your eggs are in one basket do if it goes pear shaped thats your biz down the cr@pper.
we're happy sticking with domestic and adding in the odd commercial as and when they come in.
