SPD workflow loop through multi-option loopup column

One of our users has a custom list with 50+ items which contain of a UID and a contact. In a different custom library they have a lookup field where users must select one or multiple items. Based on the items that they have selected, they want to send e-mails to the contacts as selected and automatically create items in a third custom list.

We have been *granted* the task to make this work, however we do not have access to the server itself and have only been granted Site Collection Administrator permissions. I've started building a workflow in SharePoint Designer 2010, but am lacking any form of looping method.

Does anyone know a method of looping through the multi-lookup field, getting the values, and doing things with the values? I'd hate it to make 50+ checkboxes and having to explain them how to work with it.
