I need a set designer

I am looking for a set with four shooting areas. My stage play is set inside a prison. I need approximately 4 jail cells (6 by 8 feet or slightly smaller) where 2 inmates can fit in, a common area, a desk/chair/door for the warden's office, a visiting area, and a classroom of some sort. I do not have a budget as this is my first time looking for a set designer. I am currently receiving quotes. Simple is better than complex. Thank you,
