Design isn't a commodity, meaning that you will get different costs from every designer you speak to. I personally listen to your specific needs first and then put together a customized proposal based on these needs. The costs include both BRAND STRATEGY and STRATEGIC DESIGN. With this said, please provide a rough idea of what you're willing to invest, keeping in mind that the more you can invest, the more I can invest in your project. "If you think good design is expensive, you should see the cost of bad design."
