It looks like you have two wheels on the bike. What is wrong with the current wheelset? They don't look like anything spectacular that one would need to save for racing or something.
If necessary, hubs for the most part can be rebuilt, new grease, bearings, cones, axles, etc. And it is much cheaper than buying a set of wheels, and easier than building a set of wheels.
I have snagged a couple of good 700c wheelsets off of Craigslist for around $50, often requiring some lube, truing, and etc. But they pop up from time to time.
Building wheels from scratch can be time consuming, but fulfilling. And, really doesn't need any very expensive tools. My truing stand (posted elsewhere) is homemade, and a generation old. Or, some people have built wheels on the bike.
