Not entirely happy with my Handy assembly service.  Had a solid cedar gazebo to assemble...had to contact them multiple times because they only had one "pro" assigned to the job (and it takes at least 4 strong people).  The first "pro" they sent (and I use the word "pro" VERY loosely) was a complete scam artist, and ended up taking an extra $350 from us (yes, he's been reported).  The second pro (and he was definitely a pro) came out and the job was completed. 

Handy needs to check their pros more thoroughly to ensure no one else gets scammed, but they DO have some who are outstanding.
