So I now own a dye sublimation/POD Shopify app(oops!), but have no factory to fulfill. How to get a factory for fulfillment? Preferably in Asia.

I had a client who had me make a shopify app that allows users to design and add items to their store, handle fulfillment, etc. Well, he didn't pay. So now I own the app(which is about to be approved). Thankfully I have some experience running a company, so I'm confident in my abilities there. But my background is software, so finding suppliers is pretty new to me.

I've reached out to a few suppliers on aliexpress/alibaba and the like, and am trying a couple other routes.

My ideal would be pretty flat rate pricing, but I have to compete with other apps out there so I think I'm pretty restricted to Asia to hit the price point I need.

Any contacts, ideas, etc would be very much appreciated. It's not a great situation.
