there is lots and lots out there.
There are books and magazines on the subject at my local home depot. And I have watched a number of gardening shows on the subject.
All you need is a waterproof substance from sheets of plastic to concrete, a pump the right size for your idea, something pretty to cover your pump, plastic tubing, and an electrical outlet, and lots of elbow grease.
On one show I particularly liked the guy build a little tiny fountain using nothing more than a plastic quart tub, the pump, and some river stone.
I'm waiting for them to come out with a solar pump like the lights you can get now days. Then I'll have a water feature. Right now running an electrical conduit from my apartment out past the parking lot to the garden would be amusing. Good luck with your project.
