Personalized Service

Duke and Duke Charity Auctions provide personalized service to all types of organizations and non-profit agencies coordinating benefit auctions. We not only provide ideas to help your auction generate additional revenues, but we can also help you avoid costly mistakes that can cost your organization money. From casual events that include the whole family to black-tie auctions filled with celebrities and politicians, Duke and Duke will tailor their style to help your cause generate the most funds possible. “Your auction is our auction.”

More than just an Auctioneer

With Duke and Duke, you receive more than an auctioneer for your event. We bring our team of professionals which include not only professional auctioneers, but professional bid assistants! We feel this makes a huge difference in the live auction, having professional bid assistants that know how to work a crowd and keep the energy and excitement in the room…which invariably results in more money raised.

At Duke and Duke, we have conducted benefit auctions for many, many different organizations. We bring a very high level of energy, enthusiasm and professionalism to our auctions. The comment we hear the most after our auctions from those in attendance is “that was so much fun!” We feel if those attending are having fun, they’re more apt to spend money and support a very worthwhile cause.

Consult on Live Auction item selection, item order, and starting bids. We know how to maximize all bidding at your event and will serve as your master of ceremonies (if you choose);  handle raffles, drawings, or other important announcements, and introductions.

Direct Cash Appeals

Conduct your Special Appeal, Fund-A-Need or other related direct cash appeal during the Live Auction portion of your event. This crucial portion of your event can raise up to 50-75% (or more) of the proceeds with no effort on your part.  We’ll consult and help you structure the most effective way to solicit money from your guests in a sensitive yet direct emotional appeal.  If you have never done this type of fundraiser at your event, we will show you how it has been used by hundreds of organizations like yours to bring in tens of thousands of dollars.

Silent Auction Management

Oversee Silent Auction portion of event by advising on starting bids and bid increments; monitoring bid sheets; encouraging active bidding via continuous announcements; and of course, closing all the silent auction sections in a clear, definitive manner to reach full potential of bidding.

Event Planning

Event planning and development meetings; progress consultations and advice  (either in-person** or by phone or email)—we’re here to answer your questions!


Train your committees/staff to assist the auctioneer, record bids, register and check-out guests as well as any other auction related duties.

Bid Calling

And, of course, we will SELL, SELL, SELL every item to the highest bidder during the Live Auction with our energetic, entertaining and commanding bid calling.
