Respected sir,
Do you need front & back design for your CD cover or only front cover with all details in your brief ??

Yes, a front and back cover design. Back cover should allow room for the track list however. A theme matched background tray would work also.

The thank you message will only be presented on the inside cover. The track list should be on both the back of the case design and the inside sleeve design

Actually I have almost complete your design in front cover,, but you need front back and inside sleeve and a back cover total three page so you should increase the project value . its very low . thank you.
