It depends on the style of the house...modern, traditional, farmhouse, etc. Maybe attach a picture? One material that holds up well to the environment is copper--that is why you see a lot of Lanterns, but solid copper is expensive and with your door set, not what you need. Barn Light Electric offers some good quality finishes and you could pick a brushed aluminum and a porcelain color for the shade. Also look at Rejuvenation, they have some good options. But it's hard not knowing your style of house!
