Just keep promoting your SFI and TripleClicks links all over the web! Also, join W3 an keep the sticker on your car or even get a car door magnet and keep X-Cards in the car.
If you get the chance to travel, consider getting some of the clothing with the logo on it and have X-Cards and gift cards ready to hand out to people you meet on the way.
Basically, it's a matter of advertise, advertise, advertise, and then advertise some more!
