Professional Logo
If you are not familiar with design, hire a college student to do it but please don##Q##t present a tacky logo and expect to be taken seriously. Make sure that if you hire someone to do your logo that they give you they main file in the original format that it was created in. It may be a .psd most likely if they do it in Photoshop. If they are not willing to give you the original file (ask up front) then take your business elsewhere. Otherwise you will always have to go to them to update or tweak your logo and they are going to want for you to pay them for it.
