Papier Millimetre United Kingdom Import and Export Companies

We are a branded merchandise company and would like a list of companies in Turkey that can print onto notebook covers.

I am based in the UK and am interested in importing A4 white photocopying paper in 70gsm, 75gsm, and 80gsm. I would appreciate if you could send me your brands of paper, company profile, and best quotes on the above product. The first order will be 1x 20ft container, and then there will be regular orders going forward on a container basis. Looking forward to your feedback soon.
