Hi pink clover:
Assuming its 3 panels each,
Casement windows =$420 per set
Grilles $ 230 per set
Toilets: 1 set 2 section lourves, = $ 200 each
So total roughly $2350
This is only an estimate as u did not mention how many panels there are,
If u require, i can send someone down to give a free actual quote. Pls advise
