Hello,
I'm Arsen and I would like to offer my designing skills. Please, first take a look at my portfolio, here at Freelancer to see my work. If you like what you see, we can continue to discuss about project you have.
As i could understand, you need logo similar to attached file. So, shape of the human brain, with lines, not too vivid colors?
Final files will include vector file as main format and from there any file and size can be delivered. Revisions are included and limitless.
Best Regards
