Also check the thread I started a couple days ago in the Mustachian Marketplace, if anyone who posted there is in your area they might be able to help.
Look for local bike swaps and other events which usually happen around this time of year. There are lots of bike nerds that save old bike parts they've accumulated, including wheels, and usually sell for a good price. If you found such a swap and brought the back wheel of your bike with you, someone there could help you match it with a front wheel for sale.
Most wheels I've seen for sale secondhand are usually just the hub/spokes/rim, so you'd also need a tire, inner tube, and a rim strip that goes on the inside of the rim to protect the tube from the spokes. You might find a used tire to match, and tubes and rim strips are cheap. Putting all of this together is no more difficult than changing a flat, and if you don't know how to do that yet find a bike nerd friend or a shop that runs a bike maintenance class to teach you.
