I ordered the same dissertation chapter from 5 services (price range: $200–$2,000). Here is what I learned.

Curiosity and bad financial decisions led me to run an experiment. Same prompt (social sciences, qualitative methods), 5 different companies, 5 price points. The Results:

• $200: Unusable. Clearly copy-pasted from a free online repository. Random citations that didn't exist. 0/10.
• $500: Decent English, terrible content. No understanding of my methodology. Basically a blog post.
• $900: Actually okay? Writer asked clarifying questions. Citations were real. Needed structural edits but the core was there.
• $1,500: Slightly better than the $900 version. Marginal gains. Not worth the extra $600.
• $2,000: Almost indistinguishable from the $1,500 version. Diminishing returns hit hard.

Conclusion: If you're going to do this (and I'm not endorsing it), the "sweet spot" seems to be the $800–$1,000 range for a chapter. Anything below is a scam. Anything above is luxury tax.
