I need about 20 illustrations for an instruction booklet. 90% of the illustrations are of existing color photos so they can be traced but not using a software (I can of course tell the difference). The rest need to be created or similar images need to be altered. If you choose to, you can also create your own original work. The illustrations need to be very schematic. No coloring needed. They must clearly show the steps for the instructions.
Attached are sample images that need to be vector illustrations.
I'm looking for simple work/drawings. Not works of art.
