Include tiles?

Reasonable

Where is ur place?

Maybe I can ask my ex worker if u around kl

Refuzed,

Generally for tiling works, the labour cost is RM4-5/sqft for 2x1 Tiles.
In your case, 3k is pretty reasonable given its inclusive of cement, sand etc.
This is assuming there is no existing tiles to be removed or any ground plane adjustment works.
Check for their previous works, to ensure quality.

As for tiles, we normally use White Horse 2x1 for porch its between RM5 to RM5.50 here in Seremban.
It can vary a bit depending on location and stock availability. At times, cheaper tiles could be due to stock clearance or 2nd Grade (minor sizing problems)
Also, you may need about 10-15% added to 275 pieces. This is for side skirting and adjustments.
