Fair hourly rate for short-term mission prep

I’m hiring a part-time helper (10–15 hrs/week for 6 weeks) to handle volunteer onboarding, background checks, med forms, supply kitting, and a couple airport runs for two 9-day teams in late June; based in Columbus. For those who’ve hired similar logistics support, what’s a reasonable hourly range you’ve paid?

In Columbus I’ve paid $22–28/hr; bump for ‘airport runs’ plus IRS mileage: Standard mileage rates | Internal Revenue Service. That 10–15 hrs/week window workable?

And budget $25–32/hr; 1.5x for ‘airport runs’ after 6pm, plus a 3-hour weekly minimum. Weekend?
