Go here to by your fuente de norte bus tickets! The guy working is very nice and helpful. From what I've heard it is a bad idea to buy bus tickets from the other bus companies.
On another note, if you take the belize city to flores bus, they drop you off in Santa Elena and then you will get a free shuttle to Flores. The free shuttle is provided by a tour company called Receptores Turisticos. They will try to get you to buy their tours/shuttles. Make sure you get a good deal and look around first!
Buena atencion
