Wall patching after fitting recessed lights

[August]

We wish to fit some ceiling recessed lights in our new home. The electrical contractor said they will fix the light and do some light patching. The rest of the work has to be done by somebody else.
I'm wondering that how many hours of work it would be for that extra patching by a third person . The electrician will install 6 + 4 + 4 LED wafer lights in the living room and two bed rooms. The ceiling has a stucco finish.

Thanks
