Design the interior of a pearl jewellery Showroom

We are Australia's oldest pearl farm. We would like a rough floor plan draw up for a pearl jewelry Showroom for starters, then once we agree on something we can get a to scale drawing to take to a shop fitter! The floor space is 7.23 wide and 12.06 meters deep. the back 2.5 meters will need a office and a walk in safe included. The feel is relaxed luxury. We are pearl producers selling direct to the public. We want to connect the provenance of the pearl, pristine environment and beauty to the retail experience whilst maintaining a "relaxed luxury" feel. being Australia's oldest pearl farm so there is a heritage element to be included.
