Turn hand-drawings into impactful illustrations in PowerPoint

Hi I'm looking to outsource the creation of impactful and cool looking illustrations for my many PowerPoint presentations at work. Today I normally make hand drawings on paper or whiteboards of the models/illustrations that I want in my presentations, before I turn them into models and illustrations in PowerPoint. I am really really fanatic with clean looking slides where everything lines up and look professional, but unfortunately I no longer have the time to keep up the level of quality! To save time and to do a better job than I'm currently doing, I'm looking to hire someone who can turn my drawings into slides for me - based on a nice and consistent design theme that I can use in all my presentations moving forward. Once I have found the right designer I plan to request 4-7 jobs pr. month. To quality for the job please convert one or two of the attached hand drawings (iphone pictures) into a nice illustration in PowerPoint in wide-screen16/9 format. The illustrations must be made in a way where I can easily add text/labels as needed. The design theme should match the following criteria: Flat looking - like iOS7 or IFTTT Clean and simple but impactful Feel free to use/suggest icons as indicators for milestones, impact reference, Flat colours on white or black/dark grey background Font - Open Sans or something similar For more input on the theme I would like to have, please see the attached UI illustrations Context for the two hand drawings is: One Way picture: An illustration of the process our company went through to align certain business units. Now/today we have alignment on paper, but we need to agree on a set of milestones to continue turn the alignment into reality over the next 12 months. Impact Overview picture: An illustration needed to indicate how 3 different projects have impact on the same set of stakeholders in the same period. Thanks Martin
