What am I doing WRONG?!

[CarolinaDG]

So, I am now entering what is approximately my 6th month of job searches. Although at first I was looking for things that I had absolutely no experience or education in. I am very frustrated. I would like to go back to grad school, but it seems like for the positions I am looking at I don't need it right this moment. But I STILL cannot find a job. Here is where I have looked:

Careerbuilder.com
Hotjobs.com
Monster.com
Idealist.org
Opportunityknocks.org
And every individual symphony/chorus/opera company, etc... I can find!

My degree is in music with a minor in business, and I have some experience in fundraising (i.e. I developed a program with Dance Marathon that ended up raising over $30,000 more than the previous year). I think that I am a wonderful entry-level candidate. I graduated Who's Who, was a member of ODK, and a member of several different volunteer orgs. I know that people get entry-level jobs... And I know that SOME people get them off of qualifications (though others seem to get them from their aunt/uncle/cousin, etc...). I'm frustrated, and I would like to know what I'm doing wrong so I can FIX it! And I probably am not thet only one.

Oh, and I should mention that I'm trying to get into development with a nonprofit, preferably an arts organization.
