Buy a basic electronics book. I'd suggest the ARRL Handbook, but there's tons of others. Or search the ARRL's website (www.arrl.org) for power supply projects. All the components you need to build such a power supply can be had at Radio Shack. With a little patience, a multimeter, and the right source of information ANYONE can build such a power supply.
Power supplies are among the easiest projects in both hobby and professional electronics. It helps to know what components are available to make your life a hell of a lot easier, like rectifiers and regulators. Many cost next to nothing but are often never used in PC power supplies, to save every last cent. Nobody should EVER use a PC power supply as a reference for building their own.
With a decent electronics book (perhaps the ARRL Amateur Radio Handbook for starters), an afternoon of experimenting, a halfway decent multimeter and a few trips to Radio Shack you can make a quality power supply for just about anything. And it's not all that difficult.
