The Ceremony

My fiance and I are (hopefully) getting married outside by my uncle and I need to figure out what that ceremony is actually going to consist of since there will be no religious mass or anything.  Any ideas?  We plan to write our own vows, but beyond that, I have nothing!  In all honesty, I wish we could just be married and skip the whole walking down the aisle, being on display in front of everyone we know.  I don't like being the center of attention and every time I think of the ceremony I feel like vomiting.  Same goes for the first dance.  Yeah, can we skip it?  Ugh.
