Social media promotions

I feel the need to write all of this down in order to keep track of it.

I have 3 facebook pages.  1 personal, 1 musician and 1 for my drum lesson business
I have two myspace pages.  1 personal, 1 business/musician related
I have my own website and domain.

Who sees these pages?  Almost no one that I want to view it.  How can I promote outside my close network and break into the unknown, the people that need drum lessons?  Start posting ads everywhere - not spending money though.  I will go to local lesson studios and apply for jobs.  Place ads on craigslist for drum lessons.

Brian Casey is a writer for ITG music which is based in Minneapolis.  Most of his work is writing music for t.v. ads.  Although the job seems cool, it would not be for me.  I feel that if I were to write that much, I wouldn't have any creativity left for my projects or students.  But I did benefit from this because I realized anything that I write, I could submit to these libraries.  It is a great way to potentially earn money with out spending a whole lot of work or time.
