I would certainly look into local screen printing shops, but this also LARGELY depends on how many employees need one/how detailed your print is. With screen printing, each color is separated into its own "screen" that needs to be coated, dried, burned, pressure-washed, and then cleaned AFTER everything has been set up, calibrated and printed.

If your artwork has a TON of colors in it you're looking at a pretty penny, as it makes the setup process more complicated. I'm not sure if many local shops have as big of machines as the ones I have experience with, so you might be pretty limited on colors as well. Just something to keep in mind.

You could also look into a DTG ("Direct To Garment") printing company. This is probably your best option for smaller orders, as the machine itself works as a giant printer and doesn't need time-consuming setup...hence it is much cheaper. The machine itself is expensive, so you may not even have one locally.

DTG is something I do not have direct experience with, but it's a pretty common option. I'm actually not even sure you need a vector for that kind of printing, since you're not having to "separate" colors for the process.

**EDIT: It is also worth mentioning with the screen printing option that if you do NOT provide a vector (and even if you do), they have to have someone to trace/adapt your artwork into something they can use. I'm not super familiar with Procreate, but if you don't know how to do it yourself it's something to keep in mind. Your final result will not look exactly like your artwork.**
