Below is a link to a simply DIY MIDI controller that I made because I was in your situation and could find a small MIDI controller that I could program to send the PC and CC messages that I wanted. In your case it would be programmed to send specific Program Change messages to recall specific presets. You could do this by simply changing all the “CC” in the code to “PC”
