Plug-in for Address Information?

Is there a plug-in which allows people (ie: commercial clients) to enter in their address details and it is displayed via quicktags, etc on a page?

For example, I’m wanting to put contact details like telephone number, fax number, company address, place of business, multimap URL – that kind of thing.

Also, if possible a check-box or something in the admin panel that says “Show address information: [X]” so the client can switch it on or off.

Many thanks!
