I need to understand what "yessir" refers to first. Let me search for more context about this application to create something similar.

I don't have information about what "yessir" is. Could you provide more details about the features and functionality of the yessir app you want me to create? For example:

• What type of application is it?
• What are its main features?
• What does it do?

I'll create a basic taxi driver startup application for you. Let me start by creating the main structure.
