Customisable Brochure Template Design

I’ve drafted an AI mock-up of a brochure and now need a professionally built template that I can reuse and adapt any time. The finished file should let me:

• Drop new photos quickly into a left-hand sidebar
• Swap in different headers that carry our company logo
• Keep a fixed bottom bar for company contact details
• Type or paste text into the centre section and have it automatically appear in the right colour, font and size every time

The template is strictly for brochures and other marketing pieces, so visual polish and brand consistency matter. I’m open on the platform—HTML/CSS, Word, InDesign or any tool you recommend—as long as the end result is easy for a non-designer to update.

I’ll provide:
• The AI mock-up for layout reference
• Brand colours, logo files and company details

You’ll provide the finished, editable template, any supporting style sheets or instructions, and a quick walkthrough so I can start using it straight away. Let me know your preferred software and turnaround time, and we can get started.
