Professional And Extensive Portfolio
Second,Any real music graphic designer will have a professional portfolio showcasing graphics created for some of their clients, from custom mixtape cover designs ,party flyers etc.
Also you want to make sure they have more the 10 examples.You need someone who has worked with all types of clients and has been business for awhile this shows you there work is versatile and that they obviously provide quality work and their not a fly by night company.
Once you purchase your design you should receive confirmation from your designer within 30 minutes to an hr to confirm your payment and go over your project details.Then the designer should have your single cover,logo, mixtape cover,or flyer finished within 1-2 days.
