OK I am - was- a designer specialising in equipment for production lines. Just 2 main customers kept me quite happy for 20 years. there aren't many lines of the type I designed for, and now my customers have dropped off- one has gone out of business, having dwindled over the last 2 years, the other has been bought up by a foreign firm, and they'll certainly move production abroad. I can't afford to scale down yet as I've got 2 children at university and one more to go through. I know I've kept my head in the sand for years, but it seemed safe enough until recently. So I've got to find enough to do for the next 4 years at least.
