Ways to find a home for dogs?

Two little dogs jumped into our truck wanting us to take them Home, but we can't find their Home. I have put ads up on Craigslist and on a couple of other local sites on the internet, and we've put up signs. We also had the pound check them to see if they're chipped, and they're not. We put signs up around the neighborhood. It's been over a week and nobody has come forward to claim them. We don't want to take them to the pound where they'll be separated and probably euthanized. I can't find a no-kill shelter anywhere close. We cannot keep them. There are so many dogs (and cats) up for adoption. How can I give these two good dogs a better chance at finding a forever home with a good owner? (Short of claiming on the evening news that we found them in a dumpster or something else dramatic and untrue!) How can we find them a good home (together) before we get any more attached to them?
