B2B & B2C Trade Website

I represent several factories and act as the middleman: buyers place full-container or retail-size orders through me, I earn a commission, then the order moves directly to the factory. I now need a website that makes this flow seamless for both wholesale (B2B) and retail (B2C) customers...
