Hello,
I can create a beautiful presentation for your architecture/construction company. I have had to make several presentations before, for academic projects and for a freelance environmental consulting presentation. I could make your presentation on Keynote with high-resolution images and gorgeous lettering and export the final result as a PDF. Alternatively, I can create a simple infographic. Regarding the format, I recommend keeping either a Keynote, powerpoint or PDF file format to switch between slides (Keynote vs Powerpoint is dependent on what operating system you use). Let me know how I can assist you.
Regards,
Sophie
