Upgrade existing draft website

I have an existing website designed for Job seekers. I have selected a theme and settled down. Now I am not able to continue due to some other work and I need help from professional designers who can take care of navigation, functionalities and everything. [login to view URL] The current page is on Wordpress. I am ready to migrate to Joomla or anyother frameworks, if you have a solid design for me. 1. Landing page clearly explains how I want the theme should be. Existing theme perfectly fits in. Suggest me if I can switch to some other theme. Because I am using a limited functionality version. 2. Second issue is, my home page looks [login to view URL] all the pages like, member signup, employer login, member login looks like a crap and I need you to redesign them inline with the home page design. Remember, the design should be plain and simple. 3. I have used an addin called ultimate user for new member signups. I have some issues with it. It has an inbuilt search functionality for searching new job seekers, but its not working properly. I need you to tweak it or need a new addin for new jobseeker and employer roles. 4. If the design and everything goes good, I might need improvement on SEO and other stuff. 5. Feel free to redesign the whole website. I need the design to be elegant, light and user friendly. 6. I will explain the features of employer role in detail after looking at your portfolio.
