Thrilling Novel Billboard Ad

I need a captivating electronic billboard ad to promote my new action-packed thriller novel.

Requirements:
- Eye-catching visuals
- Engaging, concise copy
- Possible inclusion of special price

I’m an indie author looking for an eye-catching 15-second billboard ad to promote my new thriller. It will run on 2 screens, located around the corner from each other: i.e., 123 Broadway above a storefront and a rooftop screen at 140 Broadway. The only difference is their screen sizes (dimensions provided below). I will provide the book cover high-res JPEG, any blurbs requested, the website address, and anything else required based on our communications. I'm on a reasonably short time frame, so I'm not looking for a protracted contest or drawn-out project. I would consider 2 different ads if I can meet the price from my limited indie author budget.

Billboard screen requirements are: PHOTO: 2026 px Wide X 1126 px Height or 16:9 proportions, @ 72 PPI, format ".jpg" or ".jpeg" or “.png”. Maximum size of 200 Mb. PHOTO: 1,188 px Wide X 814 px Height or 16:9 proportions, @ 72 PPI, format ".jpg" or ".jpeg" or “.png”. Maximum size of 200 Mb.

Thank you.
