Try to check out the local Facebook groups, too. I think we have a lot of members who live nearby you who'd be happy to help you for a small fee.
Also, any convertible shop near you should be able to do it. But honestly, replacing the Crossfire top is one of the easiest tops to replace.
There are videos on YouTube. It is best done with two people.
Watch the videos a couple of times before beginning and I am positive you can do it yourself.

What top did you buy?
