1. put your face and name on the main page of your site. Adding a personality will boost your response rate. Get rid of those generic clip images.
2. I don't like the way you present those 3 options on the top of your site. Get rid of it and place those below within..the copy. Somewhere after you have introduced yourself and your site. When placing it in the copy you also allow yourself more room to expand on what those options mean. Multipe options on a site usually confuse the visitor unless presented well.
The length depends on what you're trying to sell. The higher the item price - the more copy you need.
If you goal is to sell them on your services on the main page -go for long copy. If your initial goal is to ask for a signup to your newsletter (and it's free) then you can better pull this off with 1 - 2 pages of copy.
