Soldering pipes is one of those things that you might shy away as being too hard to learn, or something only the "pros" know how to do. But with the right tools and just a little bit of practice, it's a very useful home improvement skill to have.

For soldering copper pipe, you'll first need to pick up a couple of tools, as well as few supplies (in addition to whatever pipe and fittings you need). They're not expensive, and you can get them wherever plumbing supplies are sold.
