Hourly Rate For Consulting Gig w/ 3 yrs XP?

Hey Hackers,

I'd love feedback on what you think a fair hourly rate is for a mobile developer with 3 yrs experience training a team of developers in Kotlin? It would be for 40 hrs of work a week in a month long gig.

Training may include tech talks, writing sample code, and providing code reviews. Most travel expenses will be covered as well.

Thus far, I've heard everything from $150 - $250 / hr.

Much appreciated!
