($15k) Intimate "Elopement" in Italy

Hello all! I was hoping to get some help as I'm overwhelmed with the amount of information I've come across. My fiancé and I would love to hold a symbolic ceremony in Italy with a total 11 guests (us included). I need advice on where to start! I fell in love with Hotel Villa Cipressi and Villa Monastero. However, I am open to any places that give off the same vibe (gardens + water feature). We'd like photography, videography, dinner, ceremony, etc. Should I get a wedding planner? If so, any trustworthy recs? Maybe I shouldn't go for a planner and try to get a photographer that can help with vendors and venues? The 15k (max) is for the wedding itself, accommodations and flights not included. Thanks so much!
