It's a great time to run a special like this. Offer a double session for the price of one.

Offer both an in-studio 1 hour Senior session and a 1 hour outdoor session for the price of one.

Set a price for the two mini sessions and promote it as $100 off. They have to buy this month, but the shoot can be done any time in the current year.

Include the two shoots plus a free 5x7 and digi from one image.

The client may book the mini sessions, but you could also offer them an upgrade to a full session instead of a mini session.

You should contact 3 or 4 High School Seniors from a Jr. class now. Offer them a free shoot if they become Senior Ambassadors and will actually sell sessions to they classmates. Offer them a cash or product bonus for every paid client they bring in.
