Hi,
In HikaShop bussiness, you can configure product price with ACL.
At this moment, a user from a specific group will see all prices (the public price and the private price). Only the lower price will be use when he will add the product in his cart but he can see both.
Otherwise, there is the MSRP price but in your case I am not sure that it is the right solution.
