You might calculate base on the following,
18x26xRM 15 = RM 7020.00

Then you ask the contractor, how many days and how many workers they need to get the job done. From there you can judge his labour. Then you add adhesive, transportation and etc.

Probably they can make a few k there. But sometimes opar work is like that la. No choice.

Wow the hacking and laying floor tile cost should be reduced to 40-50% to consider reasonable price.......
