Private label clothes importing United Kingdom

I have an idea of a polyester but thick and good quality waistcoat I’d like to create something similar of. I would like to do waistcoats, skirts and trousers to begin with. Could I have a rough price guide per item please, what is your MOQ, how much is shipping and how long would this take to the UK and how long would it take from design to the bulk order being complete. Thank you.
