Found this site, and it would seem to tick all the right boxes for me, I had a look on the Lotus site, and their’s seem to have less wheel time for more money.
If you already have the car, my recommendation would be a day with Andy Walsh ( clicky ) and then a LOT day at Bedford with a couple of sessions of tuition. That would be a nice safe way of getting to grips with your car on track.

I know Anthony and can recommend his teaching style and driving ability. You will learn a lot regardless of whether you are an experienced track driver or a novice.
