ENGLISH or SPANISH for JAPANESE!

Hi! I'm a girl from Madrid with a good level of english (I'm going to take the advanced exam this year, and I hope I'll pass it) that would like to start with japanese, since I love the country of Japan. I don't have any base, I just know a couple of words but I don't know any grammar. 
Of course, I know more spanish than english (after all, I'm spanish) but I think I'll be able to teach english too. 
If you're interested, write me an e-mail. I use whatsapp too!

Arigato!
