And also tell me about the extension or ports when my business is grow. then i want to install additional ports on my routers devices.

Cisco commercial products still require staff or support to configure if you don't do this yourself. As you didn't reveal what you have now as well as who configured it the discussion is hard to impossible to start unless I write "get back to who installed and setup what you have now."
