I need a split level building map created for an office.

We are currently looking for an individual to create a split level building map (similar to the examples uploaded below - if more reference is needed we can provide this). This would include 4 floors/levels within one image. This map will only highlight/include areas such as stairs, toilets and fire exits and will be presented on a interactive screen inside our office.

The building is a complex building (extensive floor plans will be provided to freelancer) that spans across 3 addresses. This map needs to simplify the floor plans but clearly mark areas of interest for those who are moving around the building.
