Repairing quarter panel - 1937 Buick

Hoping someone with body repair experience can help me.
I've been trying to repair damage in the left rear quarter panel of my 37 Buick.
The first picture shows me pointing to a low spot that is about 1/4 inch low.
The second picture shows a high spot that is about 1/4 inch high.
There do not appear to be any creases around the dent.
The dent may be as result of the car being rear ended as I did repair damage about 3 feet away from this damage.
I first hire someone to try to pull the low spot our with a weld spot dent puller. This improved the low spot a little.
I have now been trying to bump down the high spot down with a dolly behind the low spot, but nothing is moving.
Any advice would be welcome.
Thanks

It is a matter of hammer and dolly work with the proper tools, as you both have to shrink, and stretch the material to bring it back into "spec". Unfortunately, the pictures can never show what the highs and lows are, you'll need a qualified metal worker who will not look at it with his/her eyes, but feel it with their hands, work it, and rework it until it is once again perfectly smooth.

If the opposite side is undamaged, I would cut some ACCURATE profile templates in both vertical and horizontal directions out of poster board and then see how this damaged side matches up after having something to compare it to. IMO that should be your starting point..

Thanks to both for your recommendations.
