How can I own and be the founder of a child therapy business?

Hi everyone! I am wanting to be the owner of my own child adolescent therapy business. I am graduating this year with my BA in psychology, concentration in Neuroscience and minor in Biology. I do want to be a practicing child psychologist and I am incredibly interested in child development.

However, I didn't get a lot of research experience therefore instead of jumping into a PhD program after undergrad, I wanted to pursue my MBA and gain more research experience in a lab within my city. Afterwards, I wanted to then pursue my PhD in child psychology and become a child psychologist and then hopefully open up my own business from scratch and hire various child psychologists and therapists to practice under me (with me practicing as well).

The place I want to build my business on, my mom owns that certain piece of land already. I don't know if that helps or not. I hope to build it in Texas.

Does this sound like a good idea especially when it comes to my grad school? Does anyone have any recommendations on how I can make this happen. Since I am graduating this year, I really want to be able to push my plan in action properly. Thanks!
