Research Alibaba suppliers

I am looking to research the suppliers on Alibaba in order to source a particular product. Specifically, I need to source toothbrushes. I prefer to work with suppliers in China, and I am looking for more than 7 suppliers in total. I am hoping to find reliable suppliers on Alibaba in order to get the product that I need. As such, I am looking for someone who is experienced in researching suppliers, has the time to contact the prospects and follow up with them, and can provide me with a detailed list of potential suppliers.
