“What I’ve seen work well, as part of the meetup structure, is to allocate time for attendees to introduce themselves, either at the end of break or at the end of the presentation.” -Jerry – Mtn. View 

Good information to provide during an introduction is:

1) Your Background.

2) What Services or Skills you can Provide.

3) What Type of Skills, Services, or Collaboration You Would Like from Others.
