Does this area offer a steady and secure career? Or is it hard to find and keep employment in this area?

I am a graphic designer, in the field for 5 years, and my job is done 100% on the computer. I currently have a full time job which requires me to drive an hour to and from work and with the price of gas I can hardly afford it. I know for sure I can find a job telecommuting, a.k.a. working from home. I just don’t know where to start. My resume and portfolio are ready to go. Does anyone have this type of job? Advice on how to find one?

During the summer I would like to work backstage at a set design type job. Without any direct connections how can I find a job like such preferably with some pay?
I am definitely not thinking of upscale set designs such as Broadway plays but maybe summer theater camps that need set work done. Do such summer jobs even exist? I hope.
I am interested in design, mostly interior. Any suggestions of interesting job or intern type of things I can do during the summer?
I am 15 years old and live outside of NYC.
