Buying $5 for a simple vector

I need this:

1) With proportional lines so they are the same width. The curves should be even everywhere. Or you can also make this with the golden ratio if possible.

2) Has to be .ai vector.

3) Two versions: one where each stripe (4 total) are different colors (so each stripe's colors could be easily edited), version two would be just the black outlines.

** Notice the "G" in the middle. It should still look like a G.

Let me know if you can do this. Will pay as soon as job is completed.
