Looking for a Spanish teacher native from UK

I am an English teacher from Spain (and teaching English to Spaniards) and I am looking for a Spanish teacher from the UK or another English speaking country (who teaches Spanish - preferably to English speakers).
I need an exchange for didactic reasons, at high (C1-C2) teaching level. Preferably a Philologist or expert in didactic methods. I am an experienced Philologist. We could meet in Madrid if you are here, or via Skype.
