So this admi panel is for a mobile application. Which is about flash sale promotion app.
So the admin panel should have user management, CMS pages management, Flash sale update means posting new sales giving user access, and unique redeemable codes. Monitoring the codes. And many more.
SO more preferred who can make this in flutter because the mobile app is also been made in a flutter.
New freelancers are also preferred because they have time and they charge less and they do many revisions.
so good luck waiting for your responses
