This sounds like a wonderful and creative project! Here’s how I’d recommend structuring the job description to attract the right illustrator or graphic designer:
Project Overview:
We are looking for a talented illustrator or graphic designer to re-imagine a Bible study book focused on the Book of Genesis. This book currently contains hand-drawn illustrations, summaries, and family trees that help readers engage with and explore the text of Genesis in an accessible way. While the content and structure are complete, we need a fresh, unique visual style that will set this new version apart from the existing design.
Key Details:

    Current Style: The original book has a casual, handwritten aesthetic, created digitally using an iPad and Apple Pencil.
    Desired Style: We’re open to various visual directions, such as clean and minimalist, vintage and textured, or playful and bold. The key is to create a distinct look that doesn’t resemble the original. We’re looking for originality and a style that will captivate and engage the reader.
    Scope of Work: Full re-design of the entire book, including re-imagining each page’s layout, illustrations, and other graphic elements. The page count will be provided.
    Content: All written content and illustrations (summaries, diagrams, family trees, etc.) will remain the same—only the visual style will change.

Responsibilities:

    Re-create the entire book with a new, cohesive visual style that complements the content and enhances readability and engagement.
    Develop layouts, typography, and illustrations that are distinctive yet true to the spirit of a Bible study guide.
    Deliver all assets in high-resolution digital format suitable for printing and/or digital distribution.

Qualifications:

    Experience: Proven experience in book illustration, graphic design, or related fields. Familiarity with religious or educational content is a plus but not required.
    Style Versatility: Ability to adapt to various artistic styles and create an original, cohesive look that aligns with the project’s goals.
    Technical Skills: Proficiency in digital illustration software (e.g., Adobe Illustrator, Photoshop, Procreate) and a strong understanding of layout design.
    Portfolio: A portfolio that demonstrates your skill in illustration and layout design, with examples that showcase style versatility and creativity.

Project Details:

    Timeline: To be discussed, based on project scope and page count.
    Compensation: Project-based payment to be discussed based on experience and estimated completion time.

To Apply:
Please submit your portfolio and a brief proposal outlining your vision for this project’s visual style. We’re excited to collaborate with someone who can bring a fresh perspective to this meaningful content!

This job description provides a clear picture of the creative requirements and scope, ensuring that applicants understand both the freedom they have to reimagine the visuals and the importance of aligning with the book’s purpose. Good luck with your search!
