These are most of the logos I've created, I don't think much of them as I'm pretty much a beginner, but hopefully with some of the help that I've seen given on here, someone may be able to point in the right direction. (Sorry if a little big)
Seriously try and avoid using photoshop when making logos.
Try using Illustrator, as it's a vector based program which means, it can
be scaled to any size basically, where as, Photoshop is a pixel based programe and is
less easy to play about and scale the logos.
Also, try having a look at LOGOPOND
to see how professional logos look and use them as inspiration.
