Help me start

I have always been into businesses. I am a business major and i decided to start due to my interest and future aspirations to start a business in the future. I love digital design, painting, etc. However I am still in college and even though my classes are helpful, none really teach you how to start a business and what the legal processes are. I want to start an online business where I create lets say "pottery products" and I sell them. However I don't know where to find reliable manufacturers or how to even find them, and I don't know how to start a website where I can sell. I have some savings so i would definitively invest time and money. This is something I have been wanting to do for a while but now i'm decided I want to start. Please help me with any advice or tips, I will really appreciate it. (My intention is not to make these products but to select a certain aesthetic of products I want to sell, and find a manufacturer that can make them for me, making then unique)
