I'm in need of a Tic Toc expert to help navigate my growing channel (S minneapolis)

I started a tic tok channel that's blew up, 70k plus followers in 2 months, I need help setting up my merch to be sold and learning how to use tic toc in general, my channel is Brooklynice66, feel free to take a look and see if you could help me learn the basics of making money 💰. Thank you
