Woodbrains,
I have had a laugh or two reading through this. While sounding Ok some 50% of the advice has been poor. I think Custard and one or two others have been close and useful.
Me I'm 69, have 22 yrs in a self employed capacity and in my first year earned £500. In my second year I exceeded £100,000. The difference was this:-
1) I stuck to my knowledge base and did a lot of learning and exploring. I spent 20% of my time out talking, meeting having exploratory discussions with everyone. My possible customers, my competitors, advisors ( lawyer, accountant etc the accountant was most useful by a wide mark.) family, friends and BECAME UNAFRAID OF MEETING AND TALKING ABOUT ME AND MY PRODUCT.
2) I learned to cut out all the time wasters and by cut out I mean ignore
3) I understood what I could offer, what I wanted to offer and why I wanted to offer it.
4) I earned £20k + coaching others who asked me to. The first one was a shock to the system that they even asked but paid well.
5) My marketing consisted of a business card and a sort of flyer but very pointed at the function, solution and problems I could solve. eg Fitted alcove units not Master Cabinet Maker.
6) I learned that people buy from people based on trust, empathy, shared values.
7) I also learned that a JFDI attitude paid off in spades
I went on to earn a very good living with woodwork as a very frequently practised hobby. A family crisis left me retired and a widower and bored out of my skull at age 62. You can get in a lot of trouble when you feel like that.
I became interested in boxes. Not £10 cheapies from the orient but £600 to £2000 masterpieces in exotic woods.
I made the first one and gave it to my daughter full of mistakes, issues and errors to my eyes but she did not see these. I made 3 others to stretch myself and made each one better and more attractive.
10 months after I started doing this I sold one. By accident to someone I had met who liked the photographs and desperately needed a prize for a motor rally event. I made £350. Yes I was greedy but the box was quite good, great design ( stolen off the internet and modified by me). I went on to make 3 a year for him for 4 yrs. All different.
So I would say if your workshop is too small then make small things.
Forget the Cabinet Maker Master Craftsman ideal as it is not viable except for a very few and very hard to make money from. Just put it too one side.
Ignore manufactured solutions as you lack the background.
Given your training ( College of the Redwoods...good grief) trade on it. Consider boxes maybe.
Stay employed but talk to people..move up the line of contacts towards those earning much more than you. Always be selling yourself, capability and confidence that comes from that. Not in a flash way just quiet utter confidence.
You can panic later.
Stay employed for now. Maybe move to a private school. Meet a few parents. Make a stylish box for a prize and give it away but make a production of it. Pupil in the local press receiving award with you as maker in background. Yes the press will be interested.
Your first change would be to breakout of the furniture maker timewarp into something that can be done NOW. Take action.
