While I was in college, I helped run a website/freelance business.
I did not build the websites myself but what I did was look for clients and then I hired other students to build the website.
This model was successful because it allowed me to work on multiple projects simultaneously.
After graduation, I wrapped this project up because running a website business was not something I wanted to keep doing.
While I am no longer in the freelancing/website building business, I know a lot about building successful businesses. I have worked with several successful businesses to help build sustainable business systems.
