We did the same but non traditional non boring wedding
104 peeps and in my homecountry with guest from all over the world.
Ceremony should be as short as possible. (Almost) Nobody likes the church part (ceremony) Ours was outside in the sun and was great and only 20 min long.
no wedding planner but we let the place we rented take care of most. We gave them our ideas and then they proposed things.(food, flowers for table, and people they usually work with. They will have tons of connections which you should use) They worked with their caterer. We did a buffet BBQ and was perfect. Then open bar all night long (ours was in Belgium so it didnt cost us a fortune...) It is a sh*t load of work for so many people but if you are properly organized you will not have to do a thing on the wedding day besides getting drunk and enjoy yourself
Here is the order of things asap:
1. book room and church 1 year before min.
2. book photographer 1 year in advance also same for dj or band
3. create invites and send 6-4 months in advance if it is an international wedding so travel deals can be booked.
4. The rest all falls into place
I just found out today the post office lost my wedding suit ......that was being send over
