For a display you need a display authorisation from the CAA, not the advice from an anonymous bulletin board.
I am not sure how you would go about getting one, short of contacting the CAA, and the tuition which is required.
You may have more success if you post something along the lines of getting a DA on the nostalgia forum as I know that there are quite a few folks on there that do displays.
Best of luck.
