Hi Marcelo
The approximate cost of living here would be anywhere from 50,000 to 80,000 Jamaican dollars if your accommodation and travel are taken care of.
If not accommodation starts from 25,000 Jamaican dollars and no upper limit depending upon where you are going to stay. Utilities separate. You have share taxi starting 100 Ja $
Overall if you have 200,000 Jamaica dollars should suffice easily for a good month stay. You may cut corners as and when needed.
Education starts from 70,000 Ja $ per term depends on school and grade
