I’m certainly not the best around but I just happened to be reading a book about graphics and here is what I know. What the other posters told you will work but if you are creating a logo for a business you might want to create it as a vector graphic. Photoshop, as far as I know, is only for raster graphics. The difference is, vector graphics are math based and will not pixelate no matter the size, from a business card to a store sign. Adobe Illustrator is a vector program.
