Starting a mailing station thoughts?(I will not promote)

I’m a 21-year-old (M) aspiring entrepreneur currently working as an estimator for a subcontractor construction company, making $80K while attending college. I’ve managed to save about $50K and have been actively exploring business opportunities—either buying an existing one or starting my own from the ground up. My goal is to find a low-cost business where I can hire a small team to handle day-to-day operations, allowing me to balance school, spending time with my family and girlfriend, and ideally, maintaining my current job. Recently, I came across a great location with little to no competition for a mail business, which seems like a promising opportunity. However, I have no prior experience running a business and am unsure where to start. I have the vision but need guidance on whether I should move forward independently or consider franchising with PostalAnnex. (I WILL NOT PROMOTE)
