Bakken oil patch work north of the U.S. Border??

Hi guys my company is looking to expand into the Southwestern and Southeastern corners of Manitoba and Saskatchewan we currently have three excavators in our fleet one Hitachi ZX160LC and two Kobelco SK210LC's. We have a brush mulcher, hoe pack, wrist bucket, hydraulic thumb, and a digging bucket for the Hitachi. And one thumb on one of the Kobelco's, wrist buckets buckets for both, digging buckets, and rippers. We are currently looking at adding another hoe or a dozer if we can secure some work out there. We are C.O.R. certified in Manitoba and are willing to get further required certifications if we can secure some work in the oil patch.

Are there any contractors that sub out some of their work? Or should we be contacting the oil companies themselves?
