The only reason you think it's cheap is because you're thinking of the time you spend on it. No client tells you how long to spend on a logo, and it looks like you're in control of that. So why should they pay $500 because you take 30 hours to create a logo? Sure, 30 hours, such care, but I doubt I'd see a client tell you 'work 30 hours on my logo for $500' you are the one who pushes that. And once again, your professionalism is not determined about the amount you charge or how long you spend on your logo, it's the finished product. I don't think it even looks professional to backup your work by the amount you charge and time you spent on it.
