bluey: its really hard for me to tell u the prices cos it really depends on what material u choose and how many layers u want etc etc. All I can say is, for the same kinda material and quantity, it cost me only half of the price if I were to get it in SG, even after factoring delivery out to SG and installation.
perhaps it wld be better for u to call ah bee and ask directly? if u have no time to go down to her shop (though I wld suggest u to cos u need to choose materials from there to get pricing).
