Modern & Minimalist Web Mockup Design

I require a set of web mockups to be designed for our product brochure. The main aim of the brochure is to market our product, so the mockups need to be appealing and engaging.

- Adjust, refine and update existing screenshots: The task involves making adjustments to the existing app screenshots. This includes refining them and updating them with realistic looking sample data.

- Modern & Minimalist Style: I'm looking for a design that's modern and minimalist in style. This means clean, simple and functional - with no excessive decorations, bright colors or unnecessary elements.

- Multiple Mockups Needed: You'll be required to design more than 10 mockups in total. This will involve ensuring a consistent look and feel across all the designs, and making sure they all fit the modern and minimalist style.

Ideal Skills:
- Strong graphic design skills, with a keen eye for modern and minimalist design
- Experience in web mockup design and product brochure creation
- Ability to work with existing screenshots and data, and transform them into realistic looking yet stylish mockups
