I know I could probably DIY this if I could be bothered crawling around under the house and installing a fan, some ducting and a couple of vents, but there are plenty of other jobs around the house that I've got to get through as well, so this is one that I'm happy to outsource.
I'm going to get some quotes, so am wondering what ballpark I can expect for the quotes? Location is Sydney, so if any of you have first hand recommendations on who to use, that would be cool too.
