Homestays - Living with a Dominican Family?

After reading so many posts and helpful answers, I finally have a question to ask! So here goes:

I am looking to come to the DR in October/November and live with a Dominican family, mainly to practice Spanish and learn about the real culture, not what you get at resorts. That being said, I would prefer a safe area where I wouldn't have to worry about my personal safety or the safety of my belongings. Any suggestions or ideas?

About me: I'm a 23 year old male from the U.S., currently living in Santiago, Chile. I'm prettyy fluent in Spanish, about as good as a Gringo can get. :classic:

My search so far.....

Well, I've contacted several language schools and have gotten some less-than helpful replies. Most charge $400/month, but this seems extremely expensive for the DR.

Anyone have any other ideas? I have a Masters Degree in Business and might look into teaching some English or doing some volunteer work as well, if anyone knows any good companies to work with.
