I need a simple floorplan drawn up to scale in AutoCAD

I had a dimensional survey done on a two-storey semi-detached house. I have a hand-drawn sketch with dimensions in mm.

I need that drawn up to scale in dwg file that can be opened in AtutoCAD. I would like dimensions to be shown on plans and floor area of each room calculated in [m2] to one decimal place. Example dwg is provided to show what the end product should look like (this is model view only).
Brief scope of work:
- draw wall outline from the sketch provided
- indicate wall thicknesses, stairs, doors, windows etc
- populate with dimensions
- measure room floor areas
- show captions for rooms and additional comments
- hatch walls
- paste in 1:50 scale onto a template paper layout
- adjust text in paper space such as dates, title etc

I will provide a video to talk you through exactly what needs doing.
