an second SKU area in store front and Admin

i tink it's not that hard and it's present "in part" on the new RC2.
But i want to be able to show an extra SKU in store front and in and min area with a option to be able to search for it "admin/filter and store front/normal search"
how much will it cust me?
Store Front
Name: Name abc
Model: Model abc
SKU: nb02112n-test

My store still in development mode and no income yet.
i did search for some platforms but for what i want, OC is by far the best option, but i realy need that extra SKU area.
