Reusable Period Pants import request United Kingdom

I am trying to get in touch with a manufacturer who makes reusable period pants. Are you able to guide me and help contact them please?
We are looking to find out what MOQ would be. Looking for 1000 bikini style period pans and 1000 shorts. We are looking at what options of fabrics are available but currently we use organic cotton, with a pUL inner with bamboo absorbent core with stay dry top layer. Can you help point us in direct of company please?
