Design Office space of 7000 Sqfeet

I am looking for someone to design an office space of 7000 sq feet with a minimalistic style. The space should include 10 private cabins, a conference room, a play area, lockers, a cafeteria, a server room, reception and workstations. I am open to suggestions on how to best utilize the space. I have not specified a budget for this project, but I am willing to pay for quality work. Ideal candidates should have experience in office space design and a strong portfolio showcasing their previous work.
