Assuming this is a place you can easily visit again, if you want a clean picture of the painting, I could try using some Photoshop magic to combine multiple shots to remove all the reflections.
Since the reflections move depending on your angle, If you snap pictures from every angle, I could combine them in a way that gives you a clear picture.
I can’t provide you with four grand, but I could potentially give a good digital version of it at the very least.
