I need a line drawn illustration for an explainer video

Information for the business: Education portal
Industry: Education
Design details: I need a one colour line drawing (on black background) of the sketch below which it supposed to represent educational journey through life - so first image is a blackboard or something to represent school, second is something to represent university, third is something to reperesent office/work and last is something to represent vocational training. Am happy to take any suggestions on this.
It needs to be seamless as if all drawn from one piece of string pulled up from the landscape, in the style of Wimpy Kid BUT with straighter lines to get if a professional 'clean' look not overly cartoony.

I would also like an additional drawing of a person with following objects orbitting him (parent, manager,tutor) shown as icons in same style (need not be seemless). So no colouring in all of it should look like someone has drawn on a blackboard or used a whiteboard marker but cleaner.

ONLY UK BASED TO APPLY - I NEED QUICK TURNAROUND
