It's not too hard to remove a vinyl top, and it's something you can do yourself. Many will removed easily with a scraper. You'll obviously need to sand to metal, and hopefully that won't reveal too many rust pits.
I've done this before, and the biggest issue is the indentation where the vinyl top met the body. This you'd need to fill. I used Metal2Metal.
Other than that, It's fairly simple work...Good luck.
