the tools you ask about are generally within the adobe suite, if you don't know anything about illustrator, photoshop, indesign etc, don't attempt to use them to create youre logo, to be honest you won't end up with a good result and if your logo looks unprofessional, well most people will simply see the logo and not want to go with you. As Ross said, there are plenty of us designers out there, and also he's right in saying that there are a lot of "average" designers out there so check out out portfolios and see what we have already done, choose one you like, communicate with a brief, get a price, they design it and develop it and BAM! you may just have yourself a damn good logo.
