Thank you tradegirl. Yes, you are right. But I just have no any other ways start with. So, just simply start it by registered as a limited company. Then I found that I need a trade plate. And then I found that I need motor trade insurance to get the trade plate. Plus, when I am trying to register as a trade buyer in BCA, they also need the motor trade insurance certificate. All right, I got it finally. I tried 20+ providers in the past three days. Only one take my order!
It's okay. I don't mind to take the risk to get the business on track.
