Phone or message me as soon as you have a confirmed date for your ceremony and I will get back to you as quickly as I can to let you know if I am available on that date. Then we can arrange a time to meet up or speak on the phone. During our meeting I will listen carefully to everything that you want your ceremony to be and then go away and create your ceremony for you. I will send it to you to look at and together we will amend it accordingly until you are 100% happy with it.
Yes you can involve family members, friends, musicians...its your day so you can have as many or few people involved as you want.
No, a celebrant cannot and that's why anything goes and the world is your oyster. The legal bit will need to be done in advance or after the ceremony or during the ceremony that the celebrant is involved with. It costs about £50 to get married with a registrar. You will need 2 witnesses but you can keep it as low key as you want and don't have to exchange rings if you don't want to. Saving that very personal moment for your big day.
