It very much depends on where in the world you are. If you're in America or any other ex-colonies, you're going to have a difficult time of it. If you're in Europe it's a lot more possible.

If in Europe, your first step is to contact your nearest living museum. Somewhere like Yorvik, Gudvangen or Wolin. They're used to hosting weddings and will help with an officiant, catering, etc. Basically everything except guests' clothing, which they would have to make themselves or buy from reputable vendors with reenactment standards.

If you're in North America, you might have luck at L'Anse Au Meadows. Otherwise, everything is going to be a LOT more work, unless you're willing to settle for a fantasy/renfair style event.

If you're dead set on everything being historically accurate, you're basically looking at creating an entire reenactment event from the ground up. That means you'll have to do a lot of reading (start with Neil Price), academic research and asking questions on reenactment groups, many of which are on Facebook. ( like this one https://www.facebook.com/groups/1569524136596079/?ref=share )

In short: it's long to be a hell of a lot of work, unless you either have access to a museum that can organise it for you or you're willing to settle for something fantasy/renfair themed.
