Since you have a existing Hughesnet system running- all you have to do is move it to new location, and have it repointed by an installer or yourself if you are trained to do this.. checkout http://www.datastormusers.com/
along with http://www.dslreports.com/forum/sat
also- you should move to a larger dish size, at least 1.2m depending on where your going- I always go with 1.8m(6ft) to avoid degraded performance and rain fade.
also- what sat. are you on? Satmex5?, Some satellites do not reach Belize, sm5 should be fine, others need to be checked and research done before you attempt this.
Let me know if your serious, would be glad to help out.
