i need custom's info for the bahamas?

im currently in the bahamas until july. there is no pharmacies on the island. my mother was going to have my medications brought down on a private plane (the pilot works for the same company i work for). does anyone know if this will be a big deal when he goes thru customs? i was going to make sure that he had a copy of the actual prescription with him. just worried b/c i wont be in nassau where he clears customs. i dont even know who i would contact with this question... customs maybe?
