Hello.
I have seen the attached image, which is basically an final output from your hand drawn diagram.
I am information graphic designer, having experience of working with, charts, diagrams, tables. I like to design information in creative visual form, which helps readers to interpret the information easily.
My portfolio will give you an idea about the type of infographics designed.

I can create clean, visually appealing diagrams based on your hand drawn references, and present it in presentation format with headline, intro text etc.
I look forward to connect on chat to understand your requirement further and If required, I can create a sample diagram with a PowerPoint slide.
Regards
Hemal
