The LM4780 doesn't work that well single sided, you have to make too many compromises on the layout. I spent a good few hours trying. I'll see if I can find my old OPA549 layout, but it was a hard drive crash ago, and I'm not sure if I backed it up...

Download the freeware version of Eagle EE. You should be able to create a board large enough to accomodate them. I believe that a footprint for the LM3886 is in the library as well.
