if you're part of a group/coven i'd suggest your high priest and priestess as celebrant. If not, you can have a 'self-celebrated' handfasting; or if you have kids your child could celebrate (i know, sounds odd but it's a lovely touch)
as to where - my suggestion is outdoors, possibly a forest, stone circle?
You have an active community in Notts, see here for examples

Also, when... It's coming up to the solstice, and that's a great time but can be cold and wet outdoors. The ideal time would (imho) be either Imbolg, Lughnasadh or most ideal, Bealtaine.
Congrats!
