People who have a cage/roll bar....

My dads buddy does really nice work. He would rather build it from scratch because some cages you buy such as moroso its rolled tubing so it will be thinner in some spots. His shop is 10 mins across the border called T.T Fabrication. Here is a car he is doing right now.
