Rotate around, ask Fred recomend you to some other companies, contact some of the guys in your area off this board.
Word of mouth is allways best. The only marketing material I have is a regular buisness card.
Be willing to get a foot in the door with a low introductory rate, let them know from the start that it is a one day thing only.
I've heard that a few companies if Fort are looking for climbers...
