CASTELLANO FOR ENGLISH

I'm a native Spanish speaker, born in Castilla, now living in Barcelona.
I would like to do a Spanish-English exchange to refresh and improve English. I guess my level of English is intermediate. I learn it since I was a kid, I've used it at work sometimes, and I've even taught it (a lot of preparation, of course).
I'm interested in practicing conversation and some grammar review (on the fly).
Thank you
