Thank you for reaching out to us, Dmytro.
I've escalated your account information to our support team. One of our agents will reach out to you directly via support ticket to provide you with your personal link and more information about this program.
Bring Your Own Client program is currently only available for Top Rated and Rising Talent freelancers! If you are not meeting those requirements, you can still send a link to your profile to your client and they can sign up for an Upwork account and hire you for a contract. You'll be paying standard Service Fee.
