Display multiple prices for products behind login

Hi,

Please can someone make a suggestion. I have a client who wants to display his products (1000) for his clients to be able to order online. Not a shop. The challenge is that there are three different levels of pricing for three different client types, and each cannot see the others price. I can use a membership plugin to provide the security, but need a suggestion as to the display of the products with the different prices. Any ideas?

Thanks,
Jenny
