Concrete work requires a level of expertise far beyond painting or insulation installation. If you are doing more than putting concrete at the base of some poles you are putting in the ground, you should rely on a professional concrete specialist to do the work.
Concrete can crack apart if not installed properly. An company skilled at this can determine the anticipated weight load, and reinforce the concrete properly to insure years or even decades of use without any cracking or settling.
