Ultimately YOU need to know how to use Revit and what YOU need. Revit is a very flexible tool that works for all kind of links in the AEC industry and all countries and markets. You could hire the best designer in the Universe to create a template for you. It may work for them, but not for you.
I also end up editing my template all the time to fit my needs. Without using it in real life projects, you won't know if the template works for YOU.
It is like adjusting the car seat for you. You could hire the smartest person to adjust the seat, but it won't fit YOU.
When I was new to Revit I had an Architecture Revit book. It was the worst book ever since it started with and revolved a lot around setting up the template (and for other reasons). If you don't know how to use Revit in YOUR projects, you won't know what you need or want in a template. The skill to create a template is one thing. The knowledge what you want in the template is a whole other set of knowledge you need experience for.
