Hello elbeursken,
Kindly share the design specifications for the banner, if you have any reference design then you can share with me.
What will be the resolution of the banner and what will be the theme of the banners?
Kindly share your business logic so that I can understand the theme.
I have very good experience in Photoshop, Illustrator, Corel draw etc.. will give you quality design.
Lets discuss more details in private chat.
Regards
Esha
