Great concept exyle! It's really nice that there are people actively trying to stimulate the steemit economy. We need more people like you! As a self-taught graphic designer it wouldn't be anything but natural for me to offer my services. I can do the job for 250 SBD (I tend to put a lot of hours in my logos). My portfolio can be found here https://ambros3.carbonmade.com
I already have a nice idea in mind!
