Officiant/celebrant

Hello community. I was wondering how long did it take your officiant/celebrant search took to reply to you? I started searching, requested few quotes and information but no response. (Had spoke with a person I actually liked but unfortunately that person never responded after we spoke 🤷‍♀️)

The wedding is next July, but having a very busy life, I was looking on booking the celebrant this week since I'm off and won't have any time off until right before the wedding.
When I searched for all other vendors, the responses were almost immediate. Maybe celebrant/officiant are different? I'm also starting to think maybe it's the type of wedding we want that is making them not answer? I'm Muslim (strong believer in God but not in a specific religion) groom is atheist. We both respect our beliefs or none of it, so we want something that is focused on what we are, love and respect, kindness and caring human touch. I want to have a little hint of God but a non denominal ceremony. Something simple, sweet, funny but deep. Maybe my request is too much? What are your thoughts, experience?
