I need a sketchup expert

I would like a simple 3d Sketchup model of a potential new retail store (1500 square feet) X2 floors. We have floor plans measurements and photos to accompany the task.

Phase 1: Simple Sketchup room design based on floor plans, measurements and photos.

The goal is to use this SketchUp file to introduce new elements to the interior design. So there is lots of potential for the project to extend (phase 2 & 3)

Thanks and looking forward to the proposals
