I need to revamp and remodel powerpoint corporate presentation slides

Information for the business: Camp construction, maintenance, food supply, vehicles etc for iraq
Kind of design: Full presentation
Target audience: B2B Sales (Oil & gas Majors) etc
Number of slides needed: 35 approx
Data and special elements to include: Images, infographics etc
Ideas for the visual style: Clean, corporate, different to rest fo crowd, modern
Things to avoid: death by bullet point
Extra notes: I need to revamp an old corporate, very boring, 35 slides that is used as an intro of the companies services. This is both shown to clients in intro meetings and also emailed ot new leads. It is also at times printed and bound as a handover to leads.

I have attached the current, bad version and need ideas of upto to date professional slides.

I have joined the company and part of my role is sorting out all these old marketing materials
