Project Manager Pay for rehabs and prehabs??

[Marcus J Richardson]

Hello,

I would like to know once i hire a PM how much should i pay him to manage my prehabs i will be doing.  His responsibilities will be to manage the prehab and to set milestones for contractors, pulling permits, and basically just being liable for the whole prehab.  Should i give him/her a percentage of what i make from the prehab?( and how much) or should i pay a wage per hour? (and how much)  Thanks
