In defence of Professional Standards...
Roy, you may have more work than you can handle but I would guess that this is more down to word of mouth than your website. In your line of work local referrals are much more important than websites but I think you will already be aware of this. Please do not take this personal but you stuck your head above the parapet and I feel entitled to comment. Your website has many errors and omissions.

You say that you are busy so thankfully your kitchen fitting skills must be better.
I ran your home page through the W3C validator and it reports 102 errors. This is because you do not fully understand what you are doing.
With respect, it may look OK to you but to most other people it will look like what it is - a DIY website. If I was looking for a professional tradesman and I found a website like yours I would see it as someone who does not worry too much about the fine detail and who breaks many of the most basic design principles (for example three or four different fonts on your home page). Many people like me would see your website reflecting your professional standards and I am afraid that they would looking elsewhere.
I am quite handy myself and I would compare your website to the kitchen I once fitted for myself. It used the worktop joining methods you scoff at on your website but it was a good "bog standard" job. The worktops were not properly levelled and when water from the sink landed on the worktop it ran away towards the wall. I could go on about the mistakes I made but it looked OK and many well-meaning friends congratulated me on my "skills". If I had asked you for your opinion you would have had a field day but then I had the sense to keep my head down when the pros were around.
Fortunately when I next replaced my kitchen I had the sense to employ a professional and I now have a
proper kitchen. I am afraid that no matter how you look at it you do not have a
proper website.
So this cuts both ways and getting back to your biblical quote, this is not entirely appropriate because it is evident that no one has "taught you to fish". You have tried to do it yourself.
