Commercial Real Estate - Floor plan, photographs and video tour

I am looking for a professional to take photos and virtual tours of an office block in central London.

I will also require floor plans to be drawn up.

All of this is for marketing material.

I would also like arial view the building.

The office block is lower ground, ground and four floors.

The work needs to be done over a weekend as the office block is in use.

LONDON BASED - NEED TO GO TO THE BUILDING IN MAYFAIR!
