Urgent SketchUp Building Modifications Needed

I urgently need a skilled SketchUp designer to make several modifications to a building model I've created. The first draft must be completed within an hour, so promptness and efficiency are crucial.

Key Requirements:
- Add terrain around the building (accuracy is not essential)
- Construct a roof over the ramp using white stone to match the building
- Add an entrance to the building, with details provided in a reference picture
- Install a transparent glass wall
- Remove the beginning of the ramp
- Add an exit to the building

Ideal Skills and Experience:
- Proficiency in SketchUp modeling
- Ability to work quickly and efficiently under tight deadlines
- Experience with architectural design and modifications
- Good communication skills to understand and implement reference details

If you can meet these requirements and deliver a draft swiftly, I look forward to working with you!
