I had my first quote for plantation shutters (facade) and roller blinds today. Quality Blinds and Shutters (59 Crystal Street, Peterhsam ph 1300 135 831) was recommended to me by an Interior Design Lecturer.
I was happy with the quote (it was $6500) but had better get a second quote just in case. I doubt there will be huge differences. Most plantation shutters these days are between $300 - $360 sq metre.
