Selling beats is too easy these days, as producers have dozens of online sources and outlets to reach potential buyers. If you got talent and you think your beats are worth purchasing, then start posting them on YouTube, SoundClick and various other sites. Give away free "tagged" beats to build a reputation and get free promotion, you never know, a rapper might think he sounds best on your beats and purchase an entire album of beats. SoundClick is where most producers have luck selling their beats, but there is also a great deal of competition on there so it is not easy at first. Then there is RocBattle which is another great one, on the front page you will see some of the top sellers, it's amazing how well some producers do online. Create your own website and start promoting it through social media websites like Google Plus, Facebook and Twitter. Twitter is a great way to reach out to hip hop artists, as they all like to post tweets with updates on their latest music. Reach out to rappers and promote your free promotional use beats... it's not that difficult. Just build up your reputation and make sure your can pump out enough hot beats to capture the attention of artists who might potentially subscribe to your website or follow you on Twitter to get the latest beats. HUSTLE HARD!
