What a wonderful idea! Congratulations on 10 years.

First step is probably to contact a celebrant, just for a chat, see if they "get" what you're after, much like choosing one for a wedding. There's not really much else to do from there, but they'd be able to give you great ideas for good spots to do it, where to go for dinner afterwards etc! I wish we had picked our celebrant before we booked anything, she had so much local inside info.

Which coast will it be on? Our wedding celebrant is coastal and was absolutely brilliant. Brilliant.
