I need a headhunter that will help me to hire a personal assistant in Shenzhen China

You need to be able to speak Chinese and need to have access to the typical job applicant search sites such as 51jobs. You task is to find me suitable candidates that are local in Shenzhen. The pay range is at about 10k RMB per month. The personal assistant that I am looking for can speak reasonable English and can get the job done whatever that may be. Most of the tasks are related to finding and purchasing items that I need. Many of the items are a bit technical in nature, like mechanical components or electrical components.
