To start over, summoning advice?

In the past I never made a true contract with spirits. I want to start over and build new relationships with a spirit or two in order to better hone my skills in tantric, conjuration, and shadow magic. Who would you suggest I evoke to discuss a partnership with?

I suggest calling on Thoth to ask him help you stay on track, not get drawn down into unhelpful alleyways or anything that’s partially or completely fabricated by your own mind.
