Congrats!
For your wedding ceremony, if either of you is a member of a church, check and see what that church charges. It's likely to be a fairly inexpensive option. You can also check to see if a friend/relative has a nice outdoor space for the ceremony that would be big enough to accommodate all your guests.
As for honeymoons, go to Hawaii. We went with pleasant Hawaiian holidays and had to sit through a sales pitch, but it was a cheaper option to get there and we weren't obligated to only do what they offered. In fact, we didn't take any of their packages. Made our own plans and it worked out fine.
