I have undertaken commissions for both private and public sector clients. Painting commissions have been requested for Corporate Boardrooms, Wedding Presents, Retirement Presents and Anniversary Presents.
When I meet or contact the client, we discuss what is required and I will then supply sketches or drafts of a final painting.
My policy on completion is that if the painting is not what is requested, the buyer does not need to go ahead with the purchase. The deposit, however, would be forfeited.
