If you have any questions so that you can submit a winning design, feel free to ask. I will check regularly because I am really looking for the best design possible. 

Thanks for invitation.

Is there any specific size of cover. (width or height in pixels or may be in inches.)

Good question, standard 8 x 11 in portrait works best but am very open to alternatives with the right design and look.
