I am into bridal wears and accessories in Nigeria. I would like to visit China to purchase wholesale quantities of wedding gowns and others for my business. I understand that it is cheaper and be produced faster.

I have made contact with some manufacturers in China though. As it is my first time in China, can I apply for a group tourist visa to stay for 2 weeks? If I am to apply for Business visa, can you refer me to a good agent to help me procure "Invitation Letter of Duly Authorized Unit" or "Confirmation Letter of Invitation". This is because my contacts do not know me well and therefore cannot give me this requirement.
