We have had to postpone our wedding until next May, 2016. It breaks my heart to do this but we don't have any choice. Question though: when should start to book our venues, photographer, videographer, music, caterer etc? Are dates already being filled for next year? On average, how much of a deposit do we need to hold our venue, photographer, caterer, videographer, etc? Any information would be greatly appreciated. Thank you very much.
