The rates are usualy piece work, I myself have been earning around $500 per day laying commercial vinyl. You will find lots of work if you can do a bit of everything as the layers out here seem to only do one thing i.e a carpet layer does not do vinyls,,a vinyl layer does not do carpets,a laminate layer doesnt do anything but laminate. Most of the stores I have dealt with are always looking for good reliable fitters as there seems to be a shortage ,especialy if you can do everything.
Until I came out here I never toutched karndean,but have also been layingthis,,straight lay is around $12 per metre but your average job is 120m2 plus! and the prep is a lot easier than back home as the floors are in better condition.
