Brazilian Portugese Language Exchange (Boston)

I work in Boston Mon-Thurs and will be going to work in Brazil for six months starting late September/early October. I've been studying Portugese on my own but really need to practice speaking. My level is basic right now - I also speak Spanish which has helped with learning vocabulary, but without conversation practice it is very Portugñol! If you are a native speaker interested in a language exchange in person during the week or by Skype on weekends, send me a note. Or if you know of any private tutors in the Boston area, that would be helpful as well!
