United Kingdom requested private label male boxers

Hello,
I am part of a team trying to start a new brand of male boxers.
The underwear is inspired by Calvin Klein, Emporio Armani, Tommy Hilfiger
and so we are looking for quality and a high standard...
It is a luxury brand and we need samples before placing a big order.
We need to know what you are able to make and we are willing to pay for samples.
It is a big order we want to make and a long term relationship we want to build.
We need boxers in 3 colours white, black and grey and
