Ok I built a deck 9.24 sqm for my observatory. I got materials pretty cheap but all of it consisted of permapine. Materials alone came to over $1100 and that is without using more expensive decking like hard wood or permadeck etc. That did not include labour. Now for labour it would take 2 to 3 days to construct with two carpenters. I would expect a labour charge of around $120 per hour plus GST for two chippies. Slightly less if one is an apprentice or TA. It took me 2 days on my own, but I worked straight through breaks and I worked longer. So labour could be some where around $1920 to $2880 excluding GST.
It will cost more if you are using hardwood in terms of labour. It is harder to work with and requires a lot of pre-drilling. It may well take 4 days if the timber is really hard.
However somewhere around $3900 would be a practical starting point. Three quotes is definitely best. You may find with work being a little on the lean side at present that people will work for a lot less just to keep the bills paid.
Best of luck.
