Need some quick help

Im running wordpress on a clients website, and well here it is
http://www.future-connect.biz

Now I have a home page, and other pages set up that are working fine but the homepage has an error on it, and it gives me no place to enter text on it.

If I create a new page and name it home, it will show 2 home tabs, which we dont want.

I currently in my pages section, dont have a page called home set up, this just shows up due to the theme.

How can I put my own text here??
