Here's another picture of the porch surface that provides a little more detail on the stamping. The tinting is pretty cheap, but the stamping gets pretty expensive. We opted for the stamping just on the border as a cost compromise. The original plan to stamp the whole surface would have been over double the cost of a plain 'broomed' surface. The tint was relatively economical and mixes directly into the concrete as it's made. One tip is to make sure the surface is sloped away from the house to shed water.
The little pallet in the foreground is a sample of the stone that will be used on the block facing. The stone will also be used under the door sills and small pavers between the siding and porch surface:
