Meal prep cook in home

Simple grocery shopping and bulk cooking each week. This would basically be cooking for the week but just in simple form not elegant or complicated recipes. For example, on week would be to grill 5lbs chicken, bake 10 potatoes, make 1 batch rice, roast Brussel sprouts, cook 2 lbs ground turkey and chop some vegetables. Items would be very similar week to week and no recipes or multi part preparations mostly just grilling, baking or prepping fresh ingredients in bulk for the week. Would like for tasked to pick the ingredients up as well, money provided for this as well. I estimate the shopping and cooking should take no longer than 4 hrs per week. What day it’s done is flexible.
