Offering quick work for 1 person with Upwork client account. 5 minutes - $10

I'm unable to reach a freelancer on Upwork. I need someone to send that person a message.

Something generic related to work so I can confirm that the guy is actually online but is just ignoring me. Or he is actually absent.

5 minutes of your time for $10.
Paypal, or wise, or crypto whatever suits you.

Thanks!
