Put own brand on products & shipping cost

Hi everyone, I'm new on CJ.

I'd like to know if it's possible to ask the suppliers to give unbranded products to CJ (remove "sports" or "fashion" on shoes for example), then put our own brand in CJ warehouses and send it to our client or Amazon warehouses for FBA ?

Also, if I buy multiple products and send it to the same address, do I have to pay the shipping cost for each one or is it a bulk price ?

Thank you in advance.
