Revit Model of 1920, 5 storey residence in Germany

I need my original 1920 paper blueprints converted into a clean, up-to-date Revit model. The building is a five-storey, 500 m² residential block in Germany; three of the floors are identical and another one is nearly the same, so only a handful of vertical variations exist. Over the years a few partitions, door openings and service shafts moved, so the drawings no longer match the reality.

You will receive:
• High-resolution PDFs of the original plans
• My photos, mark-ups and quick sketches that flag known deviations

Level of detail must be Intermediate, meaning the model should include walls, doors, windows plus fixed furniture and sanitary fixtures. Finishes and textures are not necessary at this stage.

We will have at least two live review calls where we screen-share, walk through the model floor by floor, and agree on any tweaks. Because I need the file as soon as possible, please only respond if you can begin immediately and keep momentum until completion.

Final deliverables: the native Revit (.rvt) file reflecting the current layout with intermediate LOD, along with a DWG export of each floor.
