Perhaps, you could place the well and aeration pump closer to you power source and pipe the water and air to the pond. Small diameter pvc pipe is considerably cheaper than large diameter electrical wire.
Gully, we're on the same page here. I suggested popping well near the power source [farm] and running 700' PVC to the pond. 250' 1.5" PVC is $150-ish - plenty large enough for 25 GPM - might even get away with 1.25" which is obviously cheaper. Rent a ditch witch for $75/day. For aeration drop the 1" PVC at same time as the well run and leave both ends accessible.
Only drawback is there's still no power at the pond for light. Suppose you could go solar and batteries for light - but how often are you really going to be hanging out at the pond after dark?
PVC plan seems it would be more economical but not sure that's critical for Josh.
If it matters, the plan I described is the one I followed for my ponds and it saved me a significant $.
