My Contractor'S Quote - Worth It?

hi all,

i'm new to this forum, just got our keys to a bishan 4A and we want to make the following changes to our place:

hack away old kitchen cabinets and put in new ones

change the sinks/WC in the 2 toilets

extend the scv points across the house and into the master bed room

replace 2 foldable doors of the toilets

replace kitchen foldable door with a straight up frame

redo all the light and power sockets (got alot i think ard 20+?)

change the hall cornice sockets x4

repaint the house

change doorgrill

chemical cleaning of the house

met this guy from Ambience Aircon & Renovation who quoted me $10k flat for everything excluding the kitchen sink/stove and door grill. the contractor seems v honest, told me about things that we shouldn't get e.g. cooker hood etc. but i feel this quote is a bit high given no hacking of floor tiles, no carpentry, nothing. and we still gotta pay for our sink and stove.

is this worth it? anyone heard of this firm before? if so would really appreciate if can share ur experiences.

thanks very much!
