Obtaining a wedding license in Greece

Hi, has anyone been married in Greece?


We are from the UK and are currently putting our legal documentation together, but struggling to find out process for actually obtaining the marriage license in Greece and how long it takes on average. We want to be sure that we will have enough time once we have our documentation together.
We will be getting married on one of the islands, rather than the mainland. We do have a wedding planner and are waiting for more details from them, but in the meantime, we just want to be prepared with any timelines - grateful for any insights anyone has, please!
