You can sell your ebooks through Amazon's Kindle program or Apple's iTunes Connect, which gives you access to a large majority of the digital-book reading market and the barriers for entry are incredibly low. You don't need to invest lots of money to make this happen, but you do need to invest lots of time, not only in writing the ebooks, but in marketing them as well.
I support bootlegging – I don’t see it as being immoral or unethical in any way. I used to bootleg quite a bit in my youth, and I still do on occasion today (although not yet today in particular, I more meant “in the present”). If you want to hustle for your money, do what you must, baby. Download some software, music, movies, or other assorted digital goodness here and start slangin. It’s not an easy life, but sometimes you gotta do what you gotta do.
