Hi...
This is Stephane from Understanding PPC... For site building, it's better to use My Free Website Builder ... I think it's an Ewen Chia's freeware...

Regarding Header and Footer design, you can use gimp ... It's free image editing software...
Now, you can find you images on free PSD sites such as Official PSD or Deviant Art.... Use them along the design of your site...

Next step, take a look at you competitors' sales page try to imitate them (In the design sense) ....
Don't copy paste else you visitors will notice it... You sales copy needs to be original but must contain some basics...
The introduction
-The issue
-The work
-The solution
-The social proof (testimonials)
-The end

You need to stand yourself out of your competition...

Have a look at sites made by,
Mike Filsman
Rob Benwell
Joel Comm
...etc

You'll have an idea at how you should design your sales page

Now you have your site ready...

Download a free ftp software Coreftp... Get ftp setting from your hosting server and host your site online...

Regarding auto responder, you need to buy a good one and pay someone to install it...

Go to freelance site... There you'll get someone to install your script...

But if you are ready to install one yourself, have a look at:

Now you have your site (with a killer sales letter) and your newsletter ready...
