Modifications to a Small Revit Project

I have a small Revit project (Laboratory 3D model) that requires some updates. I would like to have someone with more experience than myself make the project look more professional and add a few elements to the drawing.
- Change Work bench material to stainless steel
- Add cabinets in-place of work benches
- Add counter top and sink
- Add Fire-Safety Cabinet
- Add 2 people working in the lab
