Home addition recommendations

Hey everyone. We live in the north hills and are looking to add a 20x30 room into our house for a golf sim/bar area. I need someone to tell us if it’s even possible, rough measurements looks like it’s within spec.

Does anyone have a few architect recommendations and a few builder recs as well. I assume we would want to go with some type of actual home builder rather than a handyman. I appreciate all the help!
