Is it a clawfoot tub or built-in? Clawfoot could go 300lbs. The one thing with refinishers is, they can make your tub look good while you're signing the check, but durability is only told by time. I would be extremely careful hiring somebody. I used Klenk's 2-part paint once and my efforts failed. You have to acid etch the enamel, neutralize it, and get it perfectly clean. The tub I did had a low spot in the back and water tended to stand there, that's where it failed. There's the issue of chips, not sure how to fill them if there's gonna be baking involved. I think porcelain is very high temp. Maybe you could have it powder coated! I think I saw an in situ process on This Old House once. They came in and did all the work in the house.
I got the cheapest steel tub I could find at HD, it's a Bootz brand. It's little more than a car fender, and you can't use abrasives on it. It has a non-skid bottom that has proven impossible to clean perfectly. Ya get what ya pay for. Good luck.
