Civil ceremony in Rome

Hello everyone,
Hoping someone may be able to provide advice. My partner & I have decided to get married in Rome, small affair 50 guests. I'm concerned as we have to marry within 6 months of receiving our Certificate of no impediment. We know our reception plans but would it be silly to proceed with all other bookings & not have a confirmed date for our ceremony? We're aiming for 23rd May 2026, civil in the town hall (Campidoglio). They have kindly said we can reserve our date in October this year. Anyone had this experience? Fyi I opted not to go with a wedding planner as budget is tight and one quote was £5,000. Thank you
