What is the best way to market a seminar and get people to pay in advance? -

The seminar starts Jan. 18, 2010. The idea is that if they pay by certain dates than it is cheaper, and we are assure a full house A part from reducing the cost, any ideas for making it worth their while to register early?Any and all ideas welcome,Thank you

Say there is a limited number of seats and that they should register early to make sure to get in.

Funny you should ask. I m holding a seminar on how to hold an effective seminar on December 20th, 2009. If you pay for your seat by the 30th of October, you save 15%. Maybe my seminar holding seminar could help you.
