Is there a Starbucks or a McDonalds in town? Those corporations have approved bike rack designs that they will put in front of their stores, and they might even put in extras around town for minimal/no charge. Starbucks has a steaming coffee cup design, McDonalds has some traditional bicycle-looking sculptures they like to use.

You could also see if there's a metal working shop in town that would make them for you (something like the 'U'-shaped ones in your picture). Lots of times you supply the materials and they'll 'process' them (tube bending, cutting, welding, etc). They may even be able to get them powdercoated, too.
