Sorry can't really help you, but as no one answered thought I would I am also in PT and although working in a private school trying to establish a suitable course to take, was in a previous life a Uk primary school teacher. I did the 'post your CV to everyone' to find my post. But i found a list ofschools here, you can narrow down the search area too; http://www.directorio.iol.pt/escolas-de-linguas--1-384-0-0.html
Good luck though if you find anything better would love to know!!!
