The pay is standard for my area and the way that they offer assignments is very straightforward and user friends, especially for those who are not too tech savvy.
Kontras
The policies can be too much and too strict for a freelance/per diem/contracted position. They like for everyone to follow policy or get punished/charged even if there is an emergency, something out of your control or the weather or road conditions are dangerous.
You might have better options and just keep this one as a back up unless you know that nothing will ever happen. They also sometimes have favorites with who they give assignments to.
