Depends where and who. Expats will charge more but are likely to take a little more pride in the work. Not to say Hats and Doms do not take pride in their work, just 1st world standards are often higher than in developing worlds and so the norm is slightly better quality, what you can and CANT see. Also a Hat is likely to charge you a daily rate of around 750 to 1250RD$ if by himself and semi established. A Dom is more likely to make a number up in his head before he's even seen the job depending on what your home looks like from the front gates and the car in the drive and how much he owes this month, anything from 500RD$ to 50000000000000000RD$. And an Expat will measure everything to the mm, work out quantities and precise quotations over a couple of days and then still get it all wrong, but do it by the book, of sorts.
I'd say in the ballpark of up to $US20 per Mtr2 is a safe guestimate out of the air.
