This sounds like a contradiction to me. Cause you are relying on the help of spirits more than yourself. Look into systems like the golden dawn, initiation into hermetics. Systems like these teach how to raise and evoke various types of raw energy to empower the subtle body and for use in ritual.
Alot of the texts that are based off these have you work with specific energies for months sometimes years before the topic of evoking spirits is even considered. The reason for this is so you don’t become dependent on power outside of your own. With the statement you made above it sounds like you are relying on the power of the spirits you evoke more than your own power. At least this is how it sounds to me.
For example evoking a spirit with the intent of gaining assistance on a goal is like hiring a professional to do a job where as evoking them to learn from them over time is akin to having the same professional teach you how to do what they do.
The later is what most of my evocation work with spirits focuses on. Sometimes this is given as knowledge in the for of new rituals,meditations, types of energy work to experiment with, or ideas to ponder on. Sometimes they show through example either with visions or manifiestions that surface over the next few weeks.
Also this thread has alot of good info if ya hit any road blocks.
