If it's just a page editor, if you know what you are doing, you can use:
I'm sure that if you post in the programming requests that someone can set this up for you for like $20 (just a guess). I used this and set it up once so that i would put the file in the url. ex: editor.php?file=index.html, etc. Then it would open up the page, and I could edit it through that. That was for a design customer of mine one time.
Good luck, silverboltz!
EDIT: This is my choice of WYSIWYG Editors, their all different and unique in their own way.
