I need to write a plan to turn my passion into business .

I am a medical student and I am passionate about acing my usmle step 1 exam (it is a medical licencing exam in the US ) all medical students know about this exam and how hard it is . I researched extensively for an Ideal study plan to prepare for the exam , I found a somewhat very good study plan and it was very cheap ,$50 including modest content and a question bank of +2000 it was a good deal and a lot of room was available to wiggle the price , because ,medical education is generally expensive . I did some humble marketing through local channels for medical students in the my country (KSA) . the profits was very good for an amateur side hustle . I want to be the Kaplanmedical of middleeast the was long entry to write . I dont know what kind of expertise I will need but , I would say a business person who can be my startup adviser . I will attache a logo I made for my advertisement . I think I will need to make a more professional one .
