1. Set all your product weights to 0.
2. Turn on the Free Shipper module.
3. Admin->Config->Shipping/Packaging->"Order Free Shipping 0 Weight Status" set to 1
4. edit the language file for your freeshipper.php shipping module to say "Shipping Calculated Separately"
And set your payment module to "authorize" instead of "capture" so that CC transactions are left "open" for you to settle later.
