A skit junkie excited for sound fx!

Just a quick hello from this newbie. I'm actually not a sound fx guru, but I am a writer and am currently working on a series of skits. I had purchased sound fx years ago when I performed the skits, but now I am editing the skits to put them into professional format to sell as a skit book and needed a resource to send my buyers to for their sound effects since it would be a mess to include the ones I had used. Now I have a free resource I can recommend to them. And btw, anyone know just HOW I do that? I could look it up, but I feel lazy.

Clarification: I am not planning on embedding the sounds into my e-book. I am only going to suggest this website as a great place for them to find their own sound fx to use. I will list specific sounds available at this time from this site as suggestions as well.
