I was thinking of doing the same thing, make money with my music off the internet, but my stroy is differnet. I'm raising a family and had almost abandoned my dreams long ago of "making it" in the business. I was looking for nothing big, just a chance to share my music and hopefully make a living from it. Lots of sites let you post your music and videos and I have mine on a few, including my own, but because of money issues, my progress has been slow. I havne't put my heart into it enough I realize, but that'll change. There are sites that let you raise money through your fan base like Pledgemusic and Kickstarter. and it's free to start a campaign. I've thought of doing this to raise money.
David, good luck to you and your hope you find the success you're looking for!
