I came across this website yesterday with this great resource for planning your own ceremony. It has tons of readings, examples of vows, etc as well as several complete outlines to look at. There are both religious and non-religous options to choose from. Although I plan on tweaking things a bit, it is a great starting point! FYI- it is in PDF form and over 200 pages, so dont try to print it like I did.
I hope this helps anyone that is as lost/overwhelmed as I am! We are having a close family friend officate, so I felt completely on my own when it came to planning out the ceremony! http://www.cloud9marriages.com/uploads/yourcompleteweddingceremonyebook.pdf
