Hi there
So you want someone to teach you how to make logos, so that you can compete here against us later huh? :)
Nonetheless, I think the greater challenge of creating a logo is not the the using of Photoshop, but the thought process of finding concepts and sketching until you make something meaningful and unique. I would first talk about that, if you need a more in-depth insight. After that comes the Photoshop implementation.
You can look at my portfolio for some previous logo examples.
Best,
Stefan
