The Collingsworth Family does accept private bookings through the Harper Agency, as of 2015. All requests must be made via the online form located on the agency's website.
The contact sheet asks for information about the promoter of the event including the date and venue being booked, as well as background questions on the person or company that is requesting the Collingsworth Family to appear. Questions include inquiries about whether the location is indoor or outdoor, and if the event coordinators plan to sell tickets, or pay the group through a voluntary offering from the audience.
Potential bookers must provide an estimated budget ranging from zero to $14,000 or more. The questionnaire also requests details on other artists the requester has previously booked.
