Bargain price of a product with manufacturer on Shenzhen (China) for me.

I need someone on Shenzhen (China) that negotiate the price of a product with manufacturer, for me. I want to buy around 1000 units, for moment, of a product of Alibaba, but i found with very high price coz i'm Spanish. Price is 70 usd. I preffer that someone on China go to bargain like product will be for yourself and for China, to get a better price. I'm thinking that you can obtain more than 50% lower than me (i think that is possible around 30-35 usd or less). Or perhaps you can found another factory with same product cheaper. Bid and chat with me and i will bring the product and Manufacture. I have another 4 products more to negotiate price too, but for moment this is urgent (into this week).
