Ok ... sitting around the virtual table - Zach - your the next contestant.
What's the same is that both of our clients wanting things done in their house. Things either replaced, fixed, or updated. Our clients are wanting a result without the DIY "experience". They're not going to the big box store on the weekend because they don't have time to be at the big box store. They want to hire a professional with the expertise and experience to take care of their project and deliver a high quality result.
The biggest contrast between our clients is the budget they have and the complexity of the project. In the general contracting sphere, the projects are bigger and may involve permits, licensed subcontractors, design work, supply chain management, and much longer time horizon. My clients want me to manage the project. Zach has clients that want him to manage the work too, but they also want Zach to do the work. My clients know it's a very bad day when I have my tool belt on. Zach's clients on the other hand want him working hands on with their projects and repairs.
