Every part of the job is high precision as the customers who have that sort of money want perfection. This job is going ahead with no fixed price just by trust alone. Another Nephew has begun training this Month at Exeter college. tried to get my Grandaughter to join the firm but she decided shop work is her job. Electricians and plumbers are very high earners now. No one has bothered to take on trainees for the last 20 years and so many have retired including my 2 brothers and me who were within this family business. I just order and collect materials for something to do now.
