I really like the short and sweet website but a few testimonials couldn't hurt. Like the pictures and if you gave the address of the places they were taken they would mean more considering they is no personal names attached to them. The MORE personal you make it the more people can refer to those people.
Before you post the address of the work make sure you ask. Also it would be a good shot of you with the owners after project is completed with a Business sign in the background it just adds a nice touch.
