Either is fine:-)
It seems like you have a business that aims to rectify everything that is perceived as endemc within the tradesman industry. The most obvious seems to be to recruit people who can do the work that you are now (self admittedly) getting a little old for. If you can get a team of like-minded & well trained people and take a small slice of their fee`s whilst promoting them as your team that may work.
The reason I asked for your passion is that this will determine what you can feasibly succeed at. For example if you love writing - maybe writing a "How-To" book could be your way to fame and fortune. You might have hobbies away from work that you could turn in to a business.
The website will be a great resource for you to see what different people have going on and may provide an inspiration for your future direction
Best of Luck
