Came across this website, its a US based one. You put in your description eg, painting or mould removal etc and it gives you low, medium and high costings. I put in a few things and it seems to be a reasonable indicator, at least for the items I looked up. Just wondering if there is a similar Aussie based website? http://www.homeadvisor.com/cost/additions-and-remodels/demo-an-interior/?zip= Thanks.
