Hi - I didn't want you to think the support team was ignoring your post, and I am not speaking for the entire support team, just myself. I don't typically get involved in recommending solutions to people, except perhaps in a generic sense.
As you noted, you are looking at a third-party component to use in the Joomla! framework. While this might in fact prove to be the ideal solution for you, I would like to suggest that you consider alternate ideas such as gratis and non-gratis solutions to manage such a site. I am not suggesting that you necessarily go this route, just that you investigate it.
