I tried several modules for this such as "Custom Footer for Joomla! 1.5" and "Copyright and Current Year".

None of them could include url link and customized text in the order I wanted.

Neither could Advanced Custom Copyright Module, that's why I posted on the support forum and they provide me 2 updates (4.1 & 4.2) to do so in just a couple of hours!

Don't forget to donate, they really deserve it!
