Try searching on ebay for a bomber jacket and click the men's clothing filter. There are plenty on there. My search yeilded 3,844 items. However, since bomber jackets are usually made with leather, they do tend to run expensive. You can usually find a few at a thrift store. But, they will still probably be about $30 or more.
There are patterns you can use. I know kwik sew and vogue have a decent amount of patterns for men's jackets. As for fabric, you'd have to go with leather or something that is similar to that, such as vinyl. I wouldn't suggest working with either of these unless you know how to tool it and have the tools. You could make it with suede, but you would have to interline it with a twill, canvas, or sturdy interfacing to get the right weight. A poly lining would be good for the lining of the jacket.
Overall, you might be better off just buying one even if it is $50 or more. If you get good quality one, you could always use it as a jacket for cold weather. After all of the materials you need, you're looking at over $50 to make it. You would need jacket fabric, interfacing, lining, a zipper, thread, a white fabric for the applique, and a pattern. And, if you go with leather or vinyl and don't already have the means to work with it, you'll need tools.
