My problem is — in creating borders and depth. I'm graphic designer, working in Illustrator and Photoshop, but i don't know how can i realise this task. Please help me - give some advise, please.

Here SVG file: link
I have to run to class, but I'll upload a tutorial to YouTube in an hour for this. If you need it now, here is a test file where I extruded the S.

Basically, I imported the .svg into blender and converted it (Alt + c) to a mesh. Then I extruded the meshes. I used a boolean modifier to delete/hollow out the middle of the S.

Here is a screencast of the process. I will upload a more comprehensive video later if needed.
