I live in Mexico and my doctor and clinic is great and the price is very very good.

Do you speak spanish? If not I can help you. I am not sure if my doc speaks english or not I think he does because he studied in the United States. The cost here is about 4,500 dls. plus meds It includes everything but the beta and blood work if needed...
I am here to help if you like
