i just got quotation of 1 contractor, my house in Klang

RM50/down light point (extra rm5 if need install each yr own purchased downlight)
RM190/AC/Heater point
RM90/Point (13A)
RM180/ astro point

the price a bit high....

not include fitting the downlight and bulb, he say add extra rm5 per piece if u need they help.
yes, hacking the wall to concel the wire and plaster back but w/o paint the wall.
according to him, he use pcv or some kind of plastic tube to cover the wire and attached below my origin normal type ceiling and lay down to the downlight points' location.
He's not simply lay down the wire on top of paster ceiling, is this normal wire-man doing?

i'm still thinking and finding another cheaper contractor....
