Ok, I guess I'll answer my own question. I found the link below that tells how to refinish bathtubs using epoxy paint. I'm still curious how much this costs if you have someone come in and do it? Anyone?

I have no clue what it costs to have someone else do it. I did it in my kids bathroom myself several years ago. It still looks great. I bought the tub and tile kit at Lowes. Follow the directions carefully and once it's done don't use any harsh chemicals to clean it. Windex with a magic sponge will do the job.

Wish I had read this first...I paid $300 to have an antique tub refinished!
