One column layout question

Hello,

I’m brand-new to WP (but an experienced HTML/CSS hand coder). I was looking to set up a one-column WP site that is geared toward very prominent advertising blocks placed into the content. Like this:

Header………………….
text text text text text….
[[Ad……Ad……..Ad….]]
text text text text text….
[[….Big Ad…………..]]
you tube video embed……..
text text text text text….
[[Ad…Ad…….Ad…….]]
Footer with ads and widgets.

The key factor is this: The ads will periodically take complete ownership of the entire left-right single-column vertical space in the body of the blog post. For an 890 pixel-wide layout, the ad block gets the entire 890. Not off to the side in a polite sidebar box… the entire 890. You can think of it like a hurdle on a race track. The viewer has to jump over the hurdle to keep reading. Not around it… over it.

If you think of how TV ads work: they show you a few minutes of programming, then the program gets completely interrupted with full-screen ads, then it goes back to programming, then more ads…

So if you can use the metaphor of a tv timeline with a blog post going down the screen representing “time”. The commercials (the ads) periodically get the entire vertical space. Then it goes back to “regular programming” as the view scrolls down further. Then it goes back to another ad block, etc.

This kind of content-ad-content-ad orchestration would go on throughout the vertical length of the blog post.

From reading into a few books on WP, I see that you can place a banner ad in the header area of a WP theme. But I want full left-right banner blocks interspersed *throughout* the blog post. And I want to be able to control when I get to break the content flow. I would be thinking something like this as I constructed a blog post:

Now I’m typing blog text…
Now I added a picture…
Now I added a full left-right Ad block…
Now I went back to typing blog text…
Now I added another left-right Ad block…
Now I went back to typing blog text…
Now I added a Youtube embed video….
NOw I went back to typing text…
Now I added another left-right Ad block…
Now I went back to typing blog text…
Now here’s the footer…

How do you go about getting this to happen in WP? What do I need to learn on the PHP/technical side of things to make this happen?

Thanks in advance. I’m new to PHP/WP, but my HTML, CSS skills are very sharp. My javascript skills are “good enough”.
