It would help to know where you are located. If you are in Sandwhich, someone from Laconia probably wouldn't go out there for a PWC. Best bet is to find someone in you area that has one and does it themselves. Ask them to do it for you and buy them a case of beer....
It isn't that hard. Here is a good article on how to do it yourself....save the money...save the beer!
Hopefully ok to show these links to help someone out....
