Looking for a Chinese product sourcing expert

I'm looking for an ongoing contact in China for helping me source the best value products at a high standard of quality Your skills and characteristics: Excellent English skills Honesty at all times Experience with sourcing industrial materials Experience with negotiating with suppliers University Education in engineering, or similar, is a bonus. The first project is a trial. The Brief I'm looking for EPDM rubber strips. This is solid, very durable but flexible rubber (with no foam) - see the picture for what this material looks like. I need strips that are 60mm to 80mm wide and 10mm high. I need bulk pricing for over 200metres in length, cut into lengths of different sizes (mostly 1m per strip). The product must be UV resistant and weatherproof, as it will be on a roof for 10 years. If you find a cheaper product with similar quantities - i.e. moulded polymer - even better! I expect you to contact and phone suppliers. You are expected to send me photos and information about the product, including performance characteristics and price. If you perform well there will be more work in the future.
