The best way is find a friend who had work done that you were impressed with and have them introduce you. That way you can get first hand experience about the quality and customer service.
This is my recommendation also. Honestly a cedar fence picket cut to size wouldn’t be difficult and would only cost $5 assuming you have a circular saw.
100%. Not to mention you probably spent $50 on this, maybe a bit more. You would have pulled your hair out thinking how much a pro would cost you and it wouldn’t be better by much.
