Free lance "sales manager"

I searched for a GPS tracker from the Alibaba website and found many suppliers in China. I sent an e-mail to a few suppliers. I received two replies on Sunday from the same person, replying on behalf of two different companies in Shenzhen.

I suspect that this person is a freelance "sales manager" whose role is to reply to inquiries.  It seems to be an entrepreneurial approach and also excellent customer service. I hope that companies in Singapore adopt the same approach and employ such "sales managers". It will create job for unemployed people.
