Can somebody tell me how an international accounting student can apply for a job in Switzerland?

I am a 30 year old accounting student living in the United States. I am almost done with my major,but It is geting hard for me to get a job in the united states because most of the companies only hire people with work permits. So, I am looking for other places to work. Switzerland seem to be a good place to live. Can any one tell me how hard it is to get a job in switzerland? is there any problems with the age? Is there any descrimination? how expensive would it be living there while I am there looking for a job? How can I apply for a job from the United States?
