logo design

looking to design a logo for the re-branding of a local sports recreation team. I am looking to have some one modify some graphics to put on a helmet, shirts, and other types of clothing. I am thinking of developing 2 to 3 different concepts with some other ideas as well. Design basis will be the head of a bull dog ( our mascot). we are looking for it to be mean looking. I have some preliminary ideas but need them to be developed by someone who can work the softward .
