Okay, having trouble with design

Hi everyone, first…

Alright, what I am trying to do is “fit” or “plugin” the blog posts inside of a design that has already been done in HTML/CSS.

So alright, if you happened to type in globe exterminators dot com and look at the template design of that site… I would want to put the articles in the content part of that site. —– And then, put the “recent posts” in a nav replacing the newsletter signup.

This would be done in …com/blog. Because as you can see, right now it looks nothing like the site.

ahhh it’s frustrating because I can’t figure out how to explain it. I basically want to create a new page to this site called /blog and have it look like the rest of the site but display the articles written in wordpress — so that the design of the site is not interrupted.

Many Thanks!!!
Joe

EDIT: btw, please don’t think I didn’t look for this information for myself. I tried! And, i’m also not asking someone to explain it detail by detail, as much as pointing me toward a good tutorial or something..
