How do I get Custom Post data from CustomPress created custom post types?

I have created a 'Services' custom post type using CustomPress so a business on the multisite can display their offering. As part of the post type, a checkbox is present to feature the service prominently on the theme.

I need to create a query of my custom post types where post type = services and where featured = checked. Then I need to loop through and display these on the featured section of the theme.

How can I go about doing this? Thanks in advance.
