Villa wedding and pool party

Hey, I’m very early in to wedding planning and we are hoping to get married this summer. We’d love a beautiful villa in a lovely setting, near the beach. If there was a small chapel on site that would be a bonus but not essential. Ideally only a couple hours from the UK. We are thinking maybe Greece or Croatia. But I literally don’t know where to start. I love the idea of a wedding at the villa, followed by a relaxing pool party the next day. I’ve found some website but hard to know if they are genuine and still don’t know where to start. Has anyone done something or planning something similar to this? If so please help. Can you point me in the direction of where to go or where to start or any good trusted websites/wedding planners abroad. I’d really appreciate the help! Thank you so much, Zoe x
