Best thing to do is look around for private owners of special motors.
Hayleys dad managed to get an absolutely immaculate Austin heavy 12/4 (in Gumdrop blue :) ) for beer money just by going over and asking the guy nicely.
My mate Ed's dad also has a vintage car and often gets asked to do weddings and doesn't charge bog all for it.
Have a mooch on an Aston or 'rarri forum and put the question forward, sometimes just the chance to show off is all the incentive people need, let alone the chance of £300 for driving your pride and joy around :)
I wouldnt give your money to a private company who would probably only give you an hour for 300 notes if I were you.
