You can get many people who 'know Dreamweaver' or any other WYSIWYG. I prefer to do all the programming myself in a code editor (or "IDE"). Because of this, I know all the code in my head - and in a bind I could work in Notepad if I had to. Typical results are 30% less lines of code, no validation errors, and visually identical as a web page.

The hand-coded file is smaller, loads faster, executes quicker, has zero errors, and is easy for a human to read later to make modifications. The validated code is problem free when viewing in every browser, including emailed newsletters.
