Wedding Venue

Hello, My partner and I are getting engaged this year and I want to start saving up now for my wedding Venue. I live on Long Island and want to have my wedding in Nassau or Suffolk county and would like to stick to a manor or country club, currently really liking Swan Lake, Westbury Manor, Glen Cove Mansion and Stonebridge Country Club, if anyone has any pricing for locations on Long Island it would be greatly appreciated, it doesn't have to be those locations, just any for me to get a general idea.
