Install new rangehood and fix oven knob

Looking for a tradesperson to do 2 jobs in the kitchen 1. The knob on the oven has fallen off. May need oven to be taken apart to re-attach so it can function correctly. Smeg oven. 2. Remove broken range hood and install new rangehood. I've purchased a new integrated hold with same measurements as the old one, so anticipate that the cupboard may only require minor shaving back or no adjustment to install
