your well off mate, i know firms down here charging about 26 supply and fix. You can still make nice money at that but we machine it on. your labour will come in around 18m2 , do 65m2 a day ( nice easy days) 2 of you and your looking at 1170 a day so im not surpriced your not getting any jobs at 40. look at it from a customer point, 200m2 job at 40 would cost them 8k, someone at 26 m2 only 5200.
