Second B2C Web Shop

Hello,

My Project currently has B2B and B2C running. Our business group would like to have a second B2C shop for special customers to use. This second B2C site would have a different catalog from the primary B2C site, but all the other functionality would remain the same. I am new to the configuration side of things, and am not sure how to accomplish this.

Can someone recommend the proper approach to accomplish this, and possibly the documentation to accomplish this?

Thanks!
