First congratulations for your awesome theme! We are very satisfying!
We have a new project and we have to meet some B2B requirements:
1) Hide prices
2) B2B customer registration and approved manual
3) We need google to NOT index the product with the prices, but index product without prices.
The price can be hidden with custom CSS or by a catalog mode. If you hide the price it would be hidden for all the products. It would not possible to show for one and hide for another.
As for the registration and indexing, you will require additional plugins, our theme does not have the features.
