how much should I pay handyman to remove sheet rock put in insulation tape and texture. Two walls/ window wall 8x11 other wall 8x13 say about 200sqft

Too many questions - is there damage behind the drywall, are there baseboards and window trim that need to be put back, any painting, is debris removal and clean up included, or are you trying to save money by doing some of it? (And who puts up textured walls anymore? They ruin resale value.)
Call 2 people and get 2 quotes, and don't just take the cheaper one. The one who specifies what he will do the most clearly, in writing.
