I'm a Celebrant and to be honest, if you want to legally get married there are only 3 things in a ceremony which are compulsory to be done legally the rest of a wedding ceremony is just part of tradition but isn't needed.

You would need a Celebrant to do the legal aspects but really it would take 5 minutes to make it official. I am doing a lot of elopements and small ceremonies which don't have a lot of the frills, it is becoming more popular than big event type weddings.

If you want to know more you can PM me if you want to.
