I will soon have two access levels to my website - paid and free. I only want the free users to see Google Ads. The Google Ad text is HTML code which I need to be able to paste directly into a module (I have a component which does this already). However, the showing of the module needs to be dependent on the user's Joomla 1.7 user group membership - if they are a member of group X then don't show, otherwise show. The module has to have the ability to appear in any of the main Joomla positions, such as sidebar, bottom, top, etc. It's a simple job but one I don't have the skills for.
The software needs to stick to Joomla standards, such as installation and backend configuration.
Please note: I MUST be able to see evidence of your prior experience with Joomla components/modules.
