I'm looking for software for my website which can do the following:

- Allow customers to register their details (all required fields can be found at www.ara-uk.com/apply.htm), and once registered, their information will be stored on an online database, viewable via an admin control panel (eg. www.mysite.com/admin).
- There also needs to be a login page which directs registered customers to a pricelist upon registration.
- I also need an integrated newsletter, which can be used to email all registered users.

I've had a look at CMS software such as Joomla!, which was recommended, but they seem to be for blogging purposes.

If anyone can point me in the direction of any software which can do this, it would be highly appreciated.

Joomla is highly customisable, im currently making a shop using it.
