What's included
The engagement
Day 0
We discuss your research question, data, and timeline. You'll know by the end of the call whether this service fits — if it doesn't, we'll say so and suggest what does.
Day 1–2
A detailed scope with total cost, timeline, and deliverables. No surprises, no scope creep — you approve before any work begins.
Agreed timeline
Annotated code, documented decisions, and a report structured so that you understand every choice. Two rounds of revisions included as standard.

Translation equivalence testing, response style analysis, and culturally-informed question framing for Turkish samples.

Pricing
Every engagement starts with a free 20-minute call. We scope it together, then quote a fixed price before you commit.
