Look for relevant Meetups / user-groups in and around your area. Contact the organizers and see if you can give a quick schpiel at their meeting. Often times groups have a policy like "whoever sponsors pizza for the meeting gets 10 minutes to pitch their company" or something along those lines. Or maybe they just ask for a donation. Or maybe they let you do it for free if you ask nice. Who knows? Just get in touch and give it a try.
