Reformatting ppt presentation slides into single format

Description

Hello,
I need assistance in converting a 130 slide power point presentation, with slides in various formats, into a single and consistent format (format provided - no requirement to create).
Specifically, and with reference to the sample material, I need - File A to be converted in the same format as the Reference file. You'll note some slides will need very little, if any work, and some may need considerable reformatting.- Delivered within 1 week from appointment (ideally)
If we work together well there will likely be further similar jobs required.
Thank you.
