Trying to save money as GC

[Rao V.]

Hi,

I have a house for flipping purpose and I have obtained some bids from GC but the numbers won't work very well in my favour if I bring in those contractors. I still plan to use plumbers/Electricians but the rest of the stuff like tile installation/carpenter work, hanging cabinet has anyone tried hiring from temp agencies who provide construction workers. will that be a cheaper route? or any other ideas other than DIY.
