I hope someone will bid on your project.
I don't have time to do it myself but I will point out a couple of things about this design.
1. Its a bit narrow limiting your useable screen real estate.
2. The menu is very limited, you can only fit a few top level pages there or it will overflow. Since users can create arbitrary numbers of pages in mojoPortal and presumably you would have child pages beneath the top level pages, the design has nothing to handle that. There is no mouse over sub menu and no vertical sub/child menu illustrated in this design so the designer/developer who takes on this project will have to improvise something for that. Also note that the menu tabs have a fixed width, it does not adapt to the page name length so a long page name could overflow the tab.
Its a nice color scheme, but there is not much "there" there in terms of style details, its very simple. There will be lots of things that need to be improvised like styling the calendar with compatible colors, forums, forms etc.
