Team Store Help

Good Morning,

I play hockey for a small college. We recently released new jerseys, which the president of the college and many alumni have reached out to me about purchasing. I can only lie so long, but I have no idea how to set up a to order store for these Jerseys. We bought them on rebirth, but that seems to costly for a large order. Should I take orders first and then place one large order, or is there a way to keep a running team store open? Thanks.

TLDR: What service can let me set up an online store for our already designed Jersey?
