Plenty of ppl do stuff like that themselves. Never had a vert but I hear the top is a complete ***** to change. If you have the tools and the time, learn to do it yourself. You'll learn something new and not pay some mechanic $500 or whatever they'll charge you to do it.
I learned to do upholstery myself last summer from research and going slow/following directions. Saved a good chunk of $$ that way.

Just because I give you advice, doesn't mean I know more than you. Its just means I've done more stupid ****.
