Would you be able to test your website and changes with target audience? I would explain what I need and how exactly to test.
I mean, I can do design more user-friendly, but without test it would be based solely on my experience and my projection of user needs. Which surely would lead to some mistakes, because some of my expectations would fail. This statement is true for any UX/UI designer of any level of exerience. If you need to make something good for specific person, the best way is to ask this person what they need and how exactly they need it. To test it then and to get rid of all wrongs.
As for visual part - I want to know a bit more about your company, it's image, it's nature and temper. So I can reflect it in design. Overall, I would want interact with you quite often in the process of redesign.
I would work for $10/h
Let's make something great ;)
