Hey Jim, welcome to PB. Your pond and goals sounds like the perfect pond to be stocked with the hybrid bluegill(HBG), channel catfish(CC) and hybrid striped bass(HSB) combination. None of these fish will reproduce very well in a small pond meaning you have to stock new ones every year or every other year. However, the fact that they don't reproduce means you can closely control how many are in your pond and this means you can prevent overpopulation and stunting. This can be a huge challenge for small ponds and typical bass/bluegill combinations.
You can expect to grow HBG to over 1 pound without much trouble, channel cats over 8 pounds and HSB to over 6 pounds in a pond that size with a quality feeding program and aeration.
Small ponds also tend to struggle with over fishing, this stocking method helps to alleviate that some.
It would be my recommendation to stock fathead minnows(FHM) in the spring. 5 pounds would be more than enough. You can then stock your HBG 2"-4"(200), CC 4"-6"(25) and HSB 6"-8"(10) later in the spring or early summer. You can then replace harvested fish as you remove them. Because of the size of your pond, draining is fairly easy. You can do this every 6 years or so and start over. The nice thing about this stocking recommendation is that it is very quick to produce quality angling. The draining and starting over doesn't have to be done, however you have to make sure you are harvesting the largest CC and HSB or they will heavily prey on your newly stocked HBG, CC and HSB. So as the pond ages, you may need to stock more advanced sized fingerlings. The good thing is, all three species are easy to find in the Midwest and fairly cheap.
As a bonus, you can stock trout(rainbows are usually best) in the fell when water temps stay below 68 degrees. You can expect good growth rates through the colder months under a feeding program and harvest the trout out before water temps climb above lethal levels in late spring.
