Hii! I am also planning on starting one and even tho I haven't started mine yet, I think u should make ur complete plan, and design stuff like ur logo, business card, thank you card, (for packing) packing bases, etc. That's what I did and soon I'm gonna get the tools to start! Again, I haven't started my business so I'm not the best person to ask, but u can search up on yt, there's a lot of great videos!
