Selling pins

Hey everyone. I want to start selling trinkets and pins and such. I want to know, since I have acrylic paintings and colored pencil drawings, should I be rendering my pieces to be made into pins? Because it has to be digitally rendered and idk if I should just trust the company to do that?

I do have procreate on my iPad so I could render them myself.

Idk, what do you guys do? Whoever sells pins haha
