There are two sweet looking new projects at WPMU Jobs as of today:
Integrate the Supporter plugin with WHMCS billing system – “I need a developer to integrate the Supporter plugin with WHMCS billing system (via quantumgateway.com) rather than using paypal.”
Puerto Rico Blog Network – “I would like to migrate two very large 2,000+ posts single WP blogs into the MU from Database to Database. Setup the network to hold at least 1,000,000 blogs with multiple domain sites.”
Go express an interest!
