IMHO a person offering his services at whatever price and you accepting at whatever price is not getting "cheated". Getting cheated is more like they tell you they're going to do it at RM10, for example, received your money but did not do it.

But, RM10 per switch sounds reasonable.

RM85 per point is OK in my opinion, as imagining there is so much hacking and plastering. I think is reasonable.

IF you are doing like 10 points in 1 room then maybe cheaper abit la.

All comes down to volume.
