Well Express has some jeans (Zach, Rocco) that are 28 waists, but the length is another matter... you could always get slightly longer and have hemmed. Whatever I choose (usually Roccos as the Zach are too skinny for me) I often shrink mine a bit for a custom fit-thogh I AM a 32/30, not as small as you... Admittedly they're around 50/sixty dollars, not 40, but that's the way the cookie crumbles.
Also after doing a web search i found that Levi's has those sizes available on line as well...
See? Looks like Levi's are your best bet right now.
