Looking to exchange my English for some Spanish

Hi I have just moved over from Scotland to work in a British school as a teaching assistant. I pretty much have no Spanish and would really like to learn! In return I can help you with speaking and writing in English. 
I can meet weekday evenings or weekends preferably in Central Madrid.
I am happy to meet over a coffee/beer and discuss a wide range of topics from music, books to politics  :)
