Where is a good place to Learn Arabic Lebanese?

I'm Lebanese, and I find it to be one of the most fascinating nationalities ever. Anyways. I'm 14, and I know this family, and they are also Lebanese, but they can speak it. I asked the brother, 17. If he can teach me the language after they get back from Lebanon this Summer. He said sure, free of charge. But, I'm desperate to learn now. If there are any free programs, podcast. Pretty much anything that can give me a little head start on the language. That'd be awesome. Thanks soooooo much.
