$37,685 ????? crazy... Id always give sky high price cause they earn my profit commission. thats what i heard from my buddies. Id only draw and give some ideas, end of the day its those contractors that are using their hand to work. Not worth spending a bomb for few ideas or drawings unless you have a deep pockets and wanna make your house like showflat. If you want reasonable price with no gimmicks and hidden cost. Best is to find direct contractors. Last time i got my carpentry work done by malaysian. i got their nos at the lift lobby when i saw them delivering carpentry to another house to install. till now im still happy with their work.
