3.Car Porch - 5002 ft ~ 8k

4.Paint internal and external - Paint Cost ~ RM 4000 / Labour indonesion worker 2500-3000 if with Chinese head 4-4500k

5. Plaster Ceiling - flat - 3 / sq ft  roughly 800 - 1500k depending on size and design.

Overall: Depending on what material the price will land on 40k,50k,70k

From the detail u provide this is rough estimation to work on your budget. Basically if u wanna work around your budget to see there is anything to actually maximize your need and cut those overhead cost. Initially i wanted to do car porch but instead i end up spending more on my living room and tiles. If there is any more question i suggest u visit his webpage cause im an IT guy so not much of renovation stuff i can explain. What he did for me was back extension with tiles, kitchen cabinet, grills and alarm system. The whole thing came up to about RM22k. I try to upload some pics once i get my digital camera back from my brother
