Layout Designer for Book Formatting Corrections (Ebook & Print)

We are seeking an experienced layout designer to finalize two specific formatting corrections for an existing book. We will provide the already formatted files for both versions. The task is short and requires immediate attention.

Specific tasks include:
1. EBook: Correct a single formatting error by adjusting the font size of the headings to ensure consistency.
2. Print Book: Adjust all margins to achieve uniformity throughout the document, as they currently vary in size.

Mandatory Requirement: The print book file is set up using Affinity software. Therefore, proficiency and experience with Affinity Publisher (or relevant Affinity suite tools) are essential for this project. Please submit your proposals, including your rates and estimated turnaround time for these corrections.
