Restricting access to site to Traders only

Our www.mldcrafts.com site is for Trade customers only and currently does not show any prices.

We would like to add in the prices but restrict access to the site to just our registered Trade customers.

The idea would be when you go to URL you see a page asking you to register with your Shop details etc. On receipt of these we then issue that person with a password that then allows them full access to the site / prices.

Is above possible ?

Two very quick and easy settings in:

ADMIN >>> CONFIGURATION >>> Customer Details...

Customer Shop Status - View Shop and Prices
Customer Approval Status - Authorization Pending
