No, you expressed yourself just fine. Can't get much more clear than "would like to hire a captain and boat."
I can't make any specific recommendations about what charters you might find in and around Haiti, but most bareboat charter companies will provide you with a captain if you want one, or you could look for a "crewed charter," which (obviously) includes crew in the cost.
This is a reputable company that arranges charters of all sorts, almost anywhere. You might try contacting them. http://ed-hamilton.com/
