(Also....Help! I have been married before, DP hasn't. I have had the big church 'thing' and naice reception etc. I had minimal input into my wedding [shame] as my mother rode roughshod over everything and chose it all, including my dress. So I actually don't know where to start. )
Its straightforward really. You and DP decide on what sort of wedding you want, and how much money can be spent on it, plus who you both want there. Then find somewhere to get married, and somewhere to celebrate. Book those.
Everything from there on in is pretty much window dressing and can be done as you wish.
My philosophy is to spend the money on the things that people really care about (food, drink to be brutal) and that will last (rings, photos), and decide what you want to do about the rest.
We had an amazing wedding in early July 2014 and we started planning late August 2013 and had more than enough time, especially if you're looking to do it cheap! "The best" suppliers can book up years in advance, but they're not the people I'd have been picking anyway due to the cost - We handmade the bunting, invites, orders of service, table decs, place names, place name holders, cake stand, table runners, flower girl wands and the food in that time for 120 people :D don't panic, just take it step by step and it'll be amazing
