Help with a website

I can study Bitweaver for about a week, but we're in a hurry. If someone can help us instruct... or even make it for us (which we are gladly to pay), we need this website done. right now, it's a total nightmarish mess:

talyst.com/portal

and we want it to look something like this:

talyst.com/portal/test

First I need instructions. I've browsed through the tutorial... but it's a tutorial for web developers, not for people. The "Blank" theme was even more horrible than what is up there.

How do I edit Modules? I can change themes, edit CSS... but no modules... where can I find those so I can add back the sign in link on top?

How do I put the Welcome <var-user> back there on top again?</var-user>
