have you ever used photoshop before? i dont know what kind of quality hes looking for, but it would be much less time consuming to just hire someone to do it. there are a lot of considerations when it comes to creating a professional logo for a business, inclusing what the logo will be used for, ie. web, print etc. you may be able to pull it off if hes just using it for web purposes, but if he needs it for print, you need to make sure your working in a high resolution, in CMYK color mode, not RGB web colors, and be sure to make the document bigger than youll ever need it printed, because photoshop cant create vector images, so if you enlarge the final product to print, it will distort and lose image quality severely.
