a high end studio is a place where lots of care was made in the ROOM, the STAFF, the GEAR. a high end studio brings in over $2k a DAY per room. i would start by working your income to be $2k a WEEK.
first thing you should do is go buy chris stones book Audio Recording for Profit: The Sound of Money

if you can get through the book and still feel like a high end studio is your bag, then you will be moving in a good direction towards it.
