I couldn't build my own house or car, not that I would want to, they are far outside my abilities or project size.

Yeh, or you could do what I do, take an afternoon when you are not doing anything else, a file that costs £5, a straight edge which you can get anywhere, a rocker plate that you can get for 3 or 4 quid, a coloured sharpie, a fivers worth of sandpaper and frog tape and do the job as well as most people that you are going to pay for will do it for a lot less money and a lot more reward.
If you can put a shelf up mostly straight, or bake a cake from a recipe you are at the right skill level to do this.
