Planning a Crazy Cool Wedding without going Crazy: Step 6
Wedding Plan Step 6: Vendors
Once you've got the timeline information that you need for everyone, you can start hiring vendors with the exact timeframe of when you'll need them. Again, categories of vendors or goods you'll need to start looking for (in order of how likely they are to be booked early, in my opinion) are:

Location
Photography
Ceremony Officiant (may be included with location)
Day-of Planner (if you feel you'll need one)
Caterer and Food Menu
Bartender and Drink Menu
Music (for both ceremony and reception)
Hair and Makeup (if you want a particular professional especially)
Dress (It's a tough call on when exactly to get this. You want to have it taken care of but you want it to fit.)
Florist
Decor
Hotel booking for travelers
Rings
