There should be no geographical barrier to the RES in West Virginia. I'm quite a ways further north than you and the RES do fine. You'll have to find a way to source them though.
If you are patient and are working on your forage base for the next year (as would be highly recommended) then you could buy 2-3" RES which easily could be shipped to you. In your pond you could buy 20-25 RES of the 2" size and in 2 years they would be spawning and you would be all set.
however for that plan to work you need no predators or very small predators stockers up till the end of the 2nd year or beginning of the 3rd season.
Pumpkinseed would work fine as well if you have a source for them.
If you have a particularly heavy winter with prolonged thick ice cover you just need to shovel or snowblow the ice to help prevent winterkill issues.
Please do NOT do any type of premade 'kit' stocking program. Forage only next year, crayfish, minnows, shiners, scuds, shrimp, whatever you can. In a smaller pond you may have control issues with bluegill, you may prefer RES or pumpkinseeds as they don't have as many spawns/yr.
Can you explain your rationale for including carp in the mix? Do you mean decorative carp (i.e. goldfish or koi?) Or do you mean a few grass carp for vegetation control?
