Umbundu Lanaguage, Angola

I plan to live part of each year in the Angolan provinces of Bié, Huambo and Benguela. I speak Portuguese and English, now need to attain a fairly high level of Umbundu because my research interest is the comparison of proverbs between Angola and Portugal.

I  am looking for three things: 1) an Umbundu course or teacher. 2), I would like to Skype with an Umbundu speaker before traveling. 3) I need Umbundu self-study materials, such as work books or recordings.

I have accumulated many Umbundu learning resources and can share with other students who are learning this language.

I thank you in advance for your help! If I can be of any help to you please let me know.
