Luxury 3500 sq ft Office Design

I need a complete interior-design consultancy package for a 3,500 sq. ft luxury modern corporate office that will seat more than 50 people. The scope is strictly design—no turnkey execution—so I expect comprehensive drawings, specifications and visualisations I can hand over to local contractors. The workplace mix includes reception, executive cabins, premium meeting rooms, open workstations and a well-appointed cafeteria/pantry. I’m looking for a refined, contemporary aesthetic that balances high-end finishes with practical space planning and efficient MEP coordination. Please base your fixed-price proposal on delivering: • Full space planning with detailed 2D layout • Concept mood boards and material palettes for a luxury modern look • Photorealistic 3D renders and a short 3D walkthrough • Ceiling, lighting and electrical layouts in AutoCAD • Furniture, carpentry and built-in joinery drawings ready for fabrication • Material and finish specifications, plus a detailed BOQ • Clean, well-layered working drawings in DWG/PDF formats I’d like to review comparable office projects you’ve handled in the 3,000–5,000 sq. ft range, along with sample technical sheets or drawing sets. Independent designers and studios across India are welcome; prior corporate work and client references will help me make a quick decision. Kindly confirm you can supply all deliverables, outline your design process, and indicate how you will keep the total fee within my stated range.
