I spoke to a woman today who's son is a musician/artist in
PR. She said that he can introduce you around and get you some contacts but then it's up to you to make it or not. She also said that the locals will tend to give the work to other locals (unless you're a smokin' player that they just want to play with).
Let me know if you're interested and I can pass along your contact info to her and she'll give it to her son.
Also, you should be fluent in spanish.
