Help Please! Valuation Required

I have inherited a 1968 4 door Morris Minor from my recently deceased mother in law. The car has been fully restored over the last few years, looks good and is in perfect working order. Unfortunately I have to sell the car and would need a specialist to value the car, specifically to determine the quality of the restoration, which is fully documented and amounted to quite a considerable sum (probably higher than the value of the car). The car is currently in Gloucester, but will be moved to Redhill in Surrey soon. Does any anybody know who near to either of these location would be able to give me an unbiased estimate of the value of the car and the best way to sell it to an appreciative new owner?
