The only two places I know nearer to you are Bristol Transmissions and also Newbury Transmissions, both respected.
I guess you could call them to see what they offer.
When my gearbox went pop I opted for a new exchange gearbox from TPS and used a local garage that I knew to change it over - from memory the gearbox was £2,600 + vat trade. I had my MAF sensor replaced and a fresh mot and the total bill came to about £4,200 incl vat but you do get everything including the F125 switch new and even the oil for the gearbox all comes with it. It was a no brainstorm for me as I knew I wanted to keep the car and still have it now.
