South Africa İmporter Company Request: High End Dress

I'm an emerging brand launching a mommy-and-me style line. I have 4 designs, each containing a mom, kid, toddler, and coordinating seersucker boy shorts. I'm looking for an ethical, sustainable manufacturer that specializes in women's and children's higher-end dresses. I'm looking to keep my minimum order quantity (MOQ) around 50 per item, but I'm open to a slightly higher MOQ if the price difference is reasonable.
