I was attempting to drill 4 post holes myself with an one-man auger and made very little progress due to the clay and rock in my area (cougarridge). I found Calgary Post Holes service on google and took a chance with them. No regrets at all, they responded to me fairly quickly and gave me what I considered to be a fair price to drill the 4 holes and did it within a day or so. They also changed their schedule for me from afternoon to mornings due to an appointment which worked out great. I would recommend them. No issues at all.
