Firstly you want to book a venue.
Have a look at a few you like, get quotes. Ideally, one that doesn't do 'packages' as you always end up paying for things you don't really need, and there are 'hidden' costs in packages. Bespoke venues are much better and fairer.
Do a rough guest list so you have an idea of numbers.
Set a budget, and then break that budget down in to categories (clothing, catering, venue, flowers, ceremony, drinks etc). Then decide how you'd like to spend your money! Some things can't be helped (such as church/humanist/registry office fees) and others are negotiable.
Decide on a ceremony type (religious, civil, humanist, pagan etc) and make sure your venue is licensed for it - or find an alternative ceremony venue (bear in mind this will likely incur transport costs from Vermont to reception venue).
Decide on catering. Sit down meal? Buffet? BBQ?
Drinks - will you do reception drinks? Wine on tables? Open bar? Toast drink?
Evening - DJ? Band? Catering?
Dress - yours, bridesmaids, groom, groomsmen etc. near these costs in mind when asking people to be involved!
Think of what you can do yourself. Can you make your own invitations? Table plan? Menu cards? Favours? Decor?
Loads to plan! Have fun!
