Can you recommend your contractor? please pm. thanks.

During the quotation process, I found out a good friend is trying to venture in ID/renovation industry. Basically, he is the coordinator, and he has some other partner/friend that will be in charge of wet work, plumbing, electrical work, etc. Therefore, I've decided to give him an opportunity (finger crossed) and hire him as my main contractor, even though his quote is not the cheapest, nor he was the most experienced. Hope I won't regret & lose our friendship upon completion

Some of the items quoted & confirmed:
Electrical Work @ RM8K+
20A socket x 9 Nos
13A socket x 34 Nos
Light point x 16 Nos
Fan point x 5 Nos
ELCB box (inclusive of Scheider ELCB)
Astro point x 1 Nos
Light installation + Fan installation
Copper wire running through pipe/corrugated tube + concealed in wall
Inclusive of Hager Stylea Switches

Remark: due to low ceiling height (9 ft) & cost restriction, there will be no plaster ceiling nor L-box. according to my friend, the price is a bit high because of drilling and concealing wire on the ceiling wall.

Plumbing & Wet Work @ RM38K+
New water piping (using Buteline PE100) from main water meter -> water tank -> kitchen/bathroom/wet area
Floor tiles removal & installation whole apartment, inclusive of bathroom 1 & 2
Bathroom 2 wall hacking & extension (currently, washing basin is outside bathroom 2. the wall will be hacked & whole bathroom extended)
Remove, supply & install new aluminium window & grill for second room, third room & bathroom 1 & 2
Removal existing wardrobe, hanging kitchen cabinet & other rubbish

Remark: price is not final because i plan to keep the living/dining broken marble flooring, which is currently covered by wooden/vinyl flooring.

Paint @ RM8K+
Wall surface smoothing & labour for painting
Exclude sealer and paint

Based on this, the initial startup cost is about RM55k. My friend assured me flexibility (eg. i can stop and remove any unwanted item if i feel regret or change my mind). With this in mind, I paid him 50% and the process begins
