I recently started working in order to land a job that is more appropriate for me however, I feel like I may need some extra help for things to run smoothly. I wanted to do a little ritual explaining what I need and what Im willing to do in return but I ran into something that I have been meaning to ask for some time now actually,

Im pretty sure who my GD is, but he doesn't really deal with the area I need help with. So, should I go to a demon who does or stick with my GD?

Talk with him about the situation and he will likely contact other Gods for you if the matter is not his area of expertise. You can also talk with Satan and ask him if he can notify a God who would be willing to assist you.
