Complication of renovation

I feel I am stucked. For all the survey that I have done, it seemed to be backfire, ended up I have too many ideas and when I discuss these ideas with various contractor that I have, most of time it is either sound silly to them ( then they will cannot do like that...like that will cause....), or ' we will just do what you want'... not helpful.
I think I have done a few mistake during this renovation process
1) Different contractor for different works. I have one doing wetworks for turning backyard to wet kitchen; one doing wiring, one doing plaster ceiling, and one doing kitchen cabinet, and another one painting.
I regreted this, I do this for obvious reason: I thought it can save cost. However... coordination is tiring and time consuming, the wiring service don't include patching work and smoothen wall, the plaster ceiling guy service don't include ceiling painting, then the wetwork guy ask why all the electrical fitting is up before the painting is done as it will affect the painting.
2) Engage cabinet guy too early. The very first deposit that I pay with regards to my new house is dining table and beds, next is kitchen cabinet at my dry kitchen area. After paying up deposit, the next weekend they come to measure, then the very next Monday the guy start doing my cabinet already. I haven't decided which fridge to get and probably eye on Fridge of brand S, rightaway they proceed to make the tall cabinet according to that size. Then they keep asking me when the cabinet can be installed. The cabinet is done in september last year, till today my wet kitchen is not quite done yet, wiring is not quite done yet, but the cabinet guy insist that the cabinet can be up despite there is no painting work, as they rush to deliver the cabinet out of their factory and get payment before Chinese New Year. 

I am upset, as it seem the cabinet guy and the wiring guy ( both handled by same contractor anyway) seem don't care about my house finishing, just want to get the so-called agreed work done and walk away. I can only pray for the after sale service is not bad if not good. My wetwork guy is good enough to concern for me, as he has engaged painting service ( though I am planning to engage another one which is much cheaper, more than RM600 difference.

3) Probably I focus on the cost so much so I end up loosing. I might have to pay extra to get another guy to finish up after one guy is done his work. All this make me Penny wise, Pound foolish.

I really feel like I have messed up.

Lighting at new house

I am not sure why its is so difficult for me to figure out the lighting coordination for my new house. I have been planning it out for nearly a month, yet still couldn't find a perfect solution for it.
While the whole area should be illuminated enough, I wish the to have different control for number of downlights for a different ambiance :
1. lighting when watching TV,
2.lighting when need to read newspaper...
3.lighting when kids is playing at the area near staircase...,
4. Lighting when guess come..(this is easiest, basically on all lights)
while also considering its impact on electrical bill later on. I have used power points, draw on the floor plan the likelihood of the lights coordination... but still I am not quite satisfied. Just when I feel its good enough, then 2-3 days later I doubt again and wanting to find alternative. Worst is after I mention to the electrician the light plan (which I thought good enough), I will go back home and think again, wondering what if....
I think the contractors is quite frus with me, keeping asking to change this and that, can't really fix my mind. Even the light shop where I bought also, I think...as I have already change lights for 2 times. and likely changing for 3rd time:P
I got to tell myself that nothing is perfect...nothing is perfect...just live with it.. arg!!!
