Thailand is cheap!! Flights are only a few hundred dollars are there are SOOO many places to stay! I am sure you will find something perfect! Try and find a location that isn't in any of the more "popular" places. They are always the best because they are quiet and tourist free!

Our wedding in the Greek Islands ended up costing LESS than what a wedding would have cost here for 100 people. That is if you take out the airfares and accomm etc. The actual day was very reasonably priced.
