Creating an outlook template - spacing problems

So I was wondering if anyone knows how I would go about defining the typable area in an Outlook template. I have a client that wants an outlook template that looks like their website, except without the html >.< so I took a screen shot of the website and edited all of the links out, but now I need to make it so that the only typable area is where the main content would exist on the website. i.e.
____________________________
|======================|
|===| this is the main content area|
|===| mmhm.. yup. main content. |
|===| etc. etc. etc. etc. etc. etc.|
|===|_______________________|
|======================|
| this is where i have links. ish. ===|
----------------------------------------------

any ideas / help / suggestions on how I would accomplish this would be greatly appreciated.
they dont like the template i made where i manually spaced over each line of the main content area because they have to press the down button so that they dont start typing in the border along the left side . they tried typing out the content in word with the spacing correct, and it appears as it should when they copy and paste the content from word to outlook, but when the email is received by anyone else its all word wrapped around and crowding up the left border area.

thanks guys
