Community Calendars - If you have an event coming up for your company that is of interest to the general community, try the local community calendars.

Community Calendars can be found on the websites of TV stations, Villages and other local sources. They normally let you post for free as long as it's not blatantly "I'm selling this". Make your listing stand out with an image that relates to your event or have a graphic designer create a .jpg of your event that acts as a picture that portrays your details and adds excitement.

If you are in the Chicago area, try www.triblocal.com - if your content is 'worthy', they might just publish you in the Chicago Tribune Local section for free.
