Advice on Wholesale Ecommerce WP Theme needed

We are looking at creating a website for a client to sell online, but only via wholesale So we need a theme whereby the pricing is hidden, until the wholesale request has been accepted by admin.

Then the wholesale buyer can buy online for delivery.

I think there are various plugins but I wondered if there was a theme that includes the main ones, or perhaps there are some plugins that just work with ANY ecommerce Woo theme.
