Clothing made to my design

I have currently around 28 designs, but am working with a designer to have around 50 garments. These will range from hoodies to sweats to tshirts and even some swim shorts.

I will be looking to have a minimum of 500 pieces on most. 75 small / 175 medium / 175 large / 75 Xlarge. although maybe less on some. I am looking for one manufacturer to handle all my needs. i have had a few prices here in the UK but i dont feel they are competative enough. Also i will be looking to get some belts, sunglasses, hats and watches made too if you can help with that.

I have designs for quotes in pdf format ready to be emailed.

Many thanks for any help
