Any suggestions for suitable mechanics for A70?

I need to get a bit of work done on my A70 and some of the people I used to use are no more. A little bit is electrical: the dashboard lights have been going down one by one and I have purchased a new clutch, but don’t have the ability to do this work myself. In the longer term, I’d also like to replace the engine (I do have the replacement). If anybody has any knowledge of suitable people in the South East, or possibly east of England, who might be able to assist, then please let me know.
