Substance designer/painter expert

We need a Substance designer/painter expert (both required) to work on materials for our models on several productions. You must be an expert with these softwares to the point you could teach some of our employees on darker areas of this software as well as complete the projects we provide you with. If you're familiar with Unity and the substance/unity workflow even better. Please provide examples of 3D work (especially materials and textures done in Substance) done and we might (if there are too many good candidates) ask you to do a live interview or video (screenshare) where you show us your work in Substance. Please be aware that our founder is familiar with this software but in some cases, you may be asked to teach him a few more complex areas of the software....so you need to be an expert.
