Personally i prefer the path of self reliance.
The whole concept of the “faustian pacts” and concepts like it such as having to sell your sould to make any headway in magick is a result of fear based concepts, political and religious agendas propagated to keep people from seeking personal power as far as i can tell. You see examples of this put in plain sight in some of the older western ceremonial magick texts.
Ritual sacrifice is a thing but not in the hollywood way most people think of. More in the sense of sacrificing of self to ones self to grow and expand such as with the myth of odin. That or through an expenditure of energy in specific practices with animal sacrifice with a repurposing of energies in a similar vain not the most pleasant experience but it yields powerful results when done correctly.
This has some resources to explore to make your own path to what you want.
