I would go the other direction. You list the painting on the gov website, they do the transactions and all of the weird taxes, fees & vat around the world, check if is stolen, where it did come from, if it is real etc etc what ever weird shit they want, all you get is the after tax money. No need for accountants nor quadruple book keeping, just do the business.
