Average cost of shipping will fall between $10 and $25. This can vary greatly due to weight, fragility due to such a variety paintings and substrate. If it falls beyond $25, I will make good on the additional cost. timing on commisions naturally be determined by the medium in which it would be painted. Of course oil painted could take as much as a 2 week cure time before shipment. Any additional needs above and beyond to make delivery happen, would have to be covered by the customer, such as expediancy and distance fees.
As much as possible, I prefer pickup or delivery whenever possible for obvious reasons of safe delivery.
