Becoming A Wedding Planner

Just wondering if you could help me with finding out what schools are accredited around the Wisconsin area. Many of the courses I have found are online courses would that be a good way to learn or is it better to have an actual classroom setting? I am trying to find out as much info as I possibly can about what my options are in this field and if there is a way to achieve a BA in this line of work. My cousin is wedding photographer and we were thinking of going into business together. I hope that you are able to help me. Thanks.
