Tommy, I really feel for you. It can be hard to get quality work done on your car at the best of times. I have found that "word of mouth" works good. You only need to find one person who you have faith in and ask them who they would recommend to do other work. A carby guy will know a good electrician who will know a good radiator shop and so on, and eventually you will have a reliable network of repairers. Some may even show you how to do the simpler parts of the repair/tuning/diagnostic process so you then slowly develop your own skills.

I have found the hardest part of repair work is having the confidence to try doing the job yourself.

As was said in this thread, it may take an hour to do a five minute job, but at least you've learnt something and you wioll be able to do it quicker and better the next time.

Hope you don't have too much grief in the future.
