User Profiles in Portals - ie restricting products to resellers

Hi There

I wish to have a reseller portal where my dealer can place orders, I have done that bit what I am struggling with is I have a number of market sectors each with its own product range, I don't want to put resellers of by having all the products on display, only those that relevant to each reseller

I have created a profile as a test with the relevant  permissions, however how do I apply that in the portal

Then how do I apply multiple profiles for different clients

Thank you
