Geometry Postulate Proof Assistance

I'm seeking a knowledgeable freelancer who can help me to prove a mathematical postulate as part of a geometry paper I need to write and get published.

The ideal candidate should be:
- Proficient in Geometry, specifically in proving postulates,
- Able to help me overcome the challenges I'm encountering, which are:
- Understanding the underlying theory,
- Applying the postulate to a proof,
- Mapping out the proof's structure,
- Experienced in writing academic papers.

Your assistance would be deeply appreciated as I find it extremely difficult to navigate through the process on my own. Having a clear and concise explanation of how to perform the proof properly is of utmost importance. This task is about completing the paper, I understand the underlying concept perfectly.
