The fairing layup is not difficult, even for a first timer. Search and read all of the posts in this forum on it. I bet there is someone in your local EAA chapter that has experience and will help.
This will make you EAB rather than ELSA. If this is the only thing of significance that you are changing, it is not a good idea to sacrifice ELSA status just to avoid this layup. Shoot, you could probably pay a Fiberglas expert to do it for you for less than the cost of this aftermarket part.
