interpreter

I need someone who can speak Japanese who can research offices ads and speak to realtors. We are trying to find an office in Japan (anywhere). That has security at the ground floor WHICH DOES NOT ALLOW NON OFFICE WORKERS UP INTO THE BUILDING WITH OUT PERMISSION. Your job would be a) Find a cheap office in a high rise building. b) said office must have security that does not allow civilians (people who do not work in the building) up stairs. c) The building must allow us to put a company name, sign, or logo downstairs in the Lobby. I will explain more after I award the job.
