Questions About Small CSS Freelance Job

[Ronald]

I got in touch with a guy who codes websites. He knows nothing about graphics, though, and wants me to give the sub-site an inviting look. I'm not exactly sure what to charge and how far I should go in terms of graphics. I imagine it will be very clean and simple. He said that, while the Life Connections software is somewhat new and has no logo/branding identity, I should probably leave that be for the time being.

Right now, it's just the basic coding with the username and password both being "admin." Feel free to take a look:

I'll have to research to brush up on CSS which I'll use for the side menu and create some submenus for easier navigation. I'm thinking of charging maybe $25 a page, since once I get some CSS formatting in place, it should be largely finished.

On a side note, I'm having a hard time finding out how to make a body background and margin background. Like on Microsoft.com for instance, the white-to-blue gradient margin wrapping underneath the body. The margin probably allows for flexibility with different monitor dimensions.
