I need to switch a PDF design to Multi-folded Brochure design

Description

Hi there,
I have a PDF designed as separate A4 pages, but I need it converted into a professional multi-fold brochure design (tri-fold or bi-fold) suitable for printing.
What I need:
Redesign the existing PDF into a multi folded brochure format
Ensure correct panel layout, bleed, and print-ready setup
Maintain existing branding, colours, and content flow
Provide final files in high-resolution PDF with bleed and crop marks, and an editable source file
Please only apply if you have prior experience in designing folded brochures for print and can deliver quickly.
Looking forward to working with you.
CheersRAJ
