You can submit items to the Dallas Business Journals BIZCALENDAR. The deadline is three weeks before publication. You can send an email to ____@____.com with "Calendar" in the subject line. This is free but there is a pay-for-use calendar also available at dallasbusinessjournal.com. For questions about the calendar, please e-mail or call Casey Smith at ____@____.com or ###-###-####.
Despite for working for www.netsuccess.com I do have relationships with contractors that take on smaller projects that could give you some information on creating a small scale social networking site for your needs.
