Sketching 4 diagrams of hospital units- measurements not needed

Hi I am looking for someone to copy 4 basic diagrams I have of 4 hospital units and make them look good! CAD software is not needed (although I don’t mind if its created in CAD as it looks great) and no measurements or accuracy that way is required. This is essentially making a electronic representation of hand drawn maps to point out interior features like bed numbers, toilets, sink location etc.
I have 4 rough drafts done in powerpoint (one shown below) which I can provide you and some associated narrative so you can get a sense of the work. One of the main things I want is to standardize the symbols used for the various features across the diagrams eg. Same symbol of sink in all 4, windows in all 4 etc. I would also like to standardize the colour coding for example isolation rooms would all be purple, bed’s would all be white or blue or whatever colour is decided on etc.
For someone who is able to design this is a simple task.
