US$100.00 only for the license. But add on your return air to Belize City, time, etc. You can certainly arrange all this yourself as long as you know which photographer to choose, can locate and book the minister, music, location, restaurant, food, flowers, liquor, etc. and find the right location for everyone to stay, where to have the ceremony and celebrations afterwards. Oh, don't forget all the time you'll spend answering all your guests questions without knowing all the right answers. You have the time and patience for all that? If so, I'd suggest you do a recce to confirm all the plans way in advance and then arrive before the wedding to make sure your instructions are being carried out. So yes, it is a very good idea to hire someone locallly to facilitate all these elements. Or buy a big bottle of anacin.
