Infographic icons/elements

Industry: Technology
Design details: Within the attached PPT file, I have mocked up five slides. The current styling/formatting has little thought given to it, as it was just proof of concept.
The first slide illustrates a journey moving through four quadrants. The individual quadrant elements/graphics/icons are then repeated and enlarged as you drill down in to each area. The priority is to have the elements/graphics/icons designed, so that:
1. they have a consistent look and feel, bearing in mind that they will be used on a coloured background (although happy to discuss alternatives)
2. AI, files that I can re-edit/re-size and export back in to PPT as and when necessary

I have left the full 5 slides in the pack, so that you understand what is to be achieved. Please note that it is just the illustrated elements that I need at this stage, I will then place in to PPT and do all necessary formatting etc. I will add some additional notes to the PPT when budget agreed.
Target audience: Sales
Ideas for the visual style: Modern/infographic style
Preferred colors: I will sort this out
Where the design will be used: PPT/Presentation
Extra notes: Please note that the coloured lines represent the journey that start by entering the "office/business"- and then flow - they could twist, expand, change direction in order to show a non-linear journey. Hence, please provide straight and corner segments - the "lines" can also twist and wrap around
