Where do you get wholesale price for rehab and contractors?

[HJ Wang]

Im starting up blank so I have no contacts. I dont know if anyone has any reference for good painters, flooring and other contractors. Also, do you guys use handyman for most of the jobs and only contractors for things handy man cant do? Im planing to rent the 2-flat house so probably low-mid end quality will be good.

btw Im in west side chicago area. the property of interest is lcoated in forest park

thanks
