You probably want to know how much this is all going to cost you. The short answer is that my sites start at $2000. The long(er) answer is that from there, it totally depends.
I’ve found—almost always—that the same job takes a different amount of time depending on the client. You only pay for the hours I work. So, the faster we arrive upon a solution, the less you pay. I feel this is the fairest option to my clients (if I work on a flat fee, I need to pad it considerably to cover possible overages). I invoice clients with detailed time tracking information, attributing my time to each step in the process.
I want to offer my clients reasonably priced design services that meet their budget. I recommend starting by filling out my project profiler. This helps me measure all the variables in the process, and helps me come up with a proposal.
