They have anagreement with Clarion Insurance, which offers great rates. If there is a particular company that you are interested in write directly to the company and ask when they will be having auditions or if it would be possible to take company class and be seen in that way. Include a resume and picture if you have one. The answer to this question depends on what job you have. Many dancers have other jobs in addition to their dance job.
Many dancers even have a few dance jobs and juggle their schedules.
Some have never had to do anything but dancing. I think the most important thing is to look for work that really excites and inspires you. Without this approach your mind and soul will not have anything to live off of. I don't think any of us aspired to be dancers because it is financially lucretive. This depends on how well and how properly you work, how well you take care of your body, how dedicated you are to keeping your body healthy and strong as you get older, and how you allow your body to heal from injuries.
