i sadly know more then i should about this topic..lol. even though im not gaia married i have been looking into it sibce its so cute. there is a thread that i will have a link to at the end. but if you want an idea here are some videos made of the weddings on youtube
gaia wedding videotheres the video and here is a thread to that shop who provides that service along with plenty of others
wedding shop herebut currently that shop has a long waiting list. so if you dont wanna wait there are other shops you can look into, and you can find them at this link
Find shops herealso you can go there and if you wanted just certain things and not a whole package. you could ask for maybe a priest and the home to do it in. Or the marriage license. And you can find someone willing to help you out. You can basically plan it on your own. If you wanted invitations or a place already made you can order those things seperately. Or you can do it for free on your own in towns outside. Or in rally..or hollywood and have the "reception" in the club there. Theres a lot of cute ideas!
like i said i know more then i should.lol
