I did not expect that finding an apparel manufacturer would be this hard

I’ve been trying for quite some time to find a manufacturer for underwire bras, ideally 2000 or less MOQ (but can be flexible), that also offers design services. You wouldn’t think that would be a hard thing, but I’m striking out. Also trying to find a sourcing agent hasn’t been a successful endeavor either. What am I missing, or does anyone have any tips? Thank you.
