Recommendations for a Good Social Community App?

[bgjyd834]

I am building an online community and want some of the social networking applications... I just don't have enough experience with PHP to know what would be good in the long run, and I have only found one ASP program. My big issue is that I want to do a co-op buying club, which means I need a shopping cart that will integrate with Quickbooks and endicia for order processing.

Anyone have good recommendations? This is what I am tinkering with at the moment:


* WordPress + Thesis + BuddyPress + ZenCart w/Zen Cart Order Mgr Mod
* Social Engine + ZenCart w/Zen Cart Order Mgr Mod
* Joomla + JomSocial + ?? Cart
* VivoSocial (DNN) + ?? Cart
* Anahita (Joomla based) + ?? Cart



Any ideas? I have a budget of about $1000 for this project and that is it.
