Floor Plan Layout of Retail Space

We are looking for a floor plan layout of our retail space and surrounding area as required by the city regulations. I have all of the dimensions and have a rough draft done up on Word showing some of what needs to be included. Bascially it is to include the physical layout and indicate where the emergency exits are located, exit signs, fire alarm pull stations, fire extinguisher locations, first aid kit, eyewash station, exit paths. The attached draft only shows the business floorplan, but I would like to expand it to add some of the site details like showing the room in reference to the rest of the building, parking areas, muster point. Preference will go to someone who has done something like this before and has a legend and something they can work from.
