My English for Driving Lessons

I'm an English teacher living here in Madrid and I want someone to teach me how to drive, obviously, you'd probably have to be a qualified driving instructor. I hold a UK licence, but I want to get some practice in over here with someone who knows what they're doing before I hire a car and write it off! If you're able to do this, i'll give you a free hour of English lessons for every free hour of driving you give me!
