I am extremely satisfied with my decision to have my Gazebo assembled professionally. 
Andrew was very professional neat and respectful. 
My Gazebo shipment was delayed and then arrived sooner than the rescheduled appointed date. I kept Andrew updated with the delivery, he did not hesitate to assemble the Gazebo earlier than the appointed date.
 I am truly thankful to him because the day of the appointment the weather forecast predicted heavy rain and thunderstorms and would have once again delayed my appointment. 
long story short, assembly was done, I am very pleased with both purchases and would do it again and recommend paying for professional assembly, money worth spending.
