Hi there Mike,
I am a specialist for logo design/branding and a featured artist.
Choosing me means your logos will have appropriate typography, composition, color theory, grid system, hierarchy, proportion etc.
From other relevant experience, I have made Google Adwords-ready banners (static and dynamic html5 ones). Also, social media assets. My weapon of choice is AI, I don't use Ps that much. I do not usually need it for logos, style guides etc.
You can check me out on both on Dribbble & Instagram - @zarelogo
I am fluent in English, so you don't have to worry about that one.
That's about it...and yes I can learn pretty much anything. You can even test on the things I don't know, with some reasonable time, and my friend Google, I think I would manage it.
Thanks,
Zarko
P.P.P.P.S My expectations would be such that I am paid the most for the thing I know most about. That would be logo design. Generally, all graphic designers add "logo design" as something they do, but in reality, it ends up looking sloppy and generic. Logo design does not come as a bonus when you finish design school, but you have to focus on that niche.
