Studio Design Assignment

hi, I have been given an assignment to list the equipment needed in a professional level recording studio which is capable of recording an orchestra, bands, solo artists and midi/computer recording. I havent really got a clue of the items I need and more importantly the quantity of things like microphones, leads, patchbays etc. I have been set a budget of £750,000 which is to cover sofas, showers, chairs, computers the lot! The acoustics and building costs etc do not have to be included. any help would be greatly appreciated thanks happy new year everyone! mike
