Pick one of the 10 people on this page and choose "Book a paid call", or describe your project to find others.

The list covers 1 company: Optum, based on profile data retrieved on October 5, 2026. Being listed here doesn't mean someone has agreed to take calls.

You choose the offer, starting at $5 per person. It includes Instant Expert's 20% fee, so an offer that pays the person $100 costs you $125. You're charged only when the person books the call or sends the answer.
What if they don't reply?
You pay nothing. Instant Expert sends follow-up reminders, and if the person hasn't booked or answered within 7 days, the request expires and any hold on your card is released. You can invite several of the 10 people on this list at once and cap your total spend, so you pay only for the ones who accept.
