I have joined several networking groups in addition to Alignable. My advice would be to set up times to sit down and have coffee, lunch, etc & learn about other people's business. People do business with those they like, know and trust. It takes time, but the results are worth it.

In addition, review ways to get the word out you are in business, not just online. Face to face is more organic and even in this day and age, seems to work well.
