Let me explain something if i may:
When you are white and live in a non white country, at times you need a local guy that is serious and knows how to resolve local problems. In this country, money resolves all problems its just that sometimes you need a little help to get things done.
A peer of mine deals with a guy on the North coast that resolves problems for him. Got a tenant that won't leave, Got a witness to something that you don't want, having a problem with an official...? Once this guy is retained, you will not have problems from your tenant.
Im not talking about anything illegal, just u gotta know the dominican way to get things done..because when it comes down to it they stick together for themselves and lookout for their own. And you live in a foreign land with u your family and maybe a few other gringos...u dont want to be in a comprimising situation..that is not why u moved here.
Excuse my ramble, although i know nothing about you, I have an understanding for the feeling of helplessness for foreigners that just come here to make a decent living.
