You choose the offer, starting at $5 per person. The offer is what the person receives, and Instant Expert's fee is added on top, so a $100 offer costs you $125. The fee is 20% of what you pay. 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.
