CRE Loaded - Email invoice for custom order to client

We are using CRE Loaded v. 6.2 Our client owns an online wig shop. They often have custom order which is easily created in the admin section of CRE Loaded, and can be edited for color, style and price. We need to be able to send an invoice for the order from the admin section once a custom order is entered. It should contain all of the information in the standard invoice, and also give a link to pay via paypal or google checkout.
