Want to creat a html email in outlook and entourage?

I want to have a html emailer that I can send my clients and friends. I have been doing the ghetto way by making all the images and links with direct path… like the this: http://www.mysite.com/emailer/images/one.gif And then I send it as a html page…

But I want to make one that is more pro. Just like this one http://iso50.com/

if you go to the bottom of the page it you will see it.

I hope this make sense… Thanks!!!
