Stunning Cover Design for 'Instagram for Business' Training Module

"Design a professional cover for a business training module titled 'Instagram for Business,' tailored for entrepreneurs, educators, and small business owners. The cover should have a bright, vibrant yellow as the dominant color to evoke energy and optimism. Include modern and clean typography for the title, and incorporate subtle social media elements like the Instagram logo, phone icons, or growth charts to reflect the digital marketing theme. The design should feel minimalistic, polished, and suitable for a professional trainer, with accents in black and white for contrast. Ensure that the overall aesthetic is sleek, modern, and inviting for a business audience."
