I would agree with what has been said above. An easy way to make some extra money is to distribute and sell your sounds online.
If I may be so bold, may I suggest Sampleism?
http://www.sampleism.com

Sampleism offers the best services around for setting up your own online store. No contracts to sign and no hassle. Manage your own sounds and request your earnings at any time. See what sells and what works and manage your own online store to suit. With a vast amount of control, the potential to reach a huge audience and automatic integration with Soundcloud there is no other place on the net that can give you the presence to sell your samples, sounds, libraries and audio collections.
You can also use Soundcloud’s technology to embed widgets, players and promotional material anywhere you like.
We are actively looking for new developers to join the community so please get in touch if you want more information – We are very keen to talk to you to find out what you like, dislike or desire and we are flexible when it comes to commission and storage needs.
We are particularly interested in Kontakt Libraries (or any sampler format).
Sorry if this sounds self-promotional (I guess it is a little) but I’m pretty sure this is a service some of you will be very keen to use.
