Hi,
i can help you to find five manufacturers in China.
And i would like to know how is the quantity of the sample you want them to product.
For facilitating the work, i need to communicate each manufacturer under the name of your company. I will ask them to present me all certificates that they have to have as a manufacturer, and i will do a responsible investigation also. And i hope you to provide me the certificate of your company or some useful info about your company for presentation to each manufacturer.
If you want them to sign a NNN agreement before initiate the project, i can ask them and can draft a NNN too, but this bid exclude the price of the draft.
Best regards
