Amir,
Too bad you were feeling a little blue about the feedback. I think you've got some great ideas and so much great material for good copy that maybe there's too much focus on design.
I've been so focused on trying to learn design lately that I forgot about some great copywriting sites I found early in my web marketing research. Just to make a point many of them use fairly crude graphics to show how good copy is more important.
I can't find my old links, but here's a great example I just found.

Here's a good example of good copy and free consulting in action. (Well, I bought it, I don't know about others.)

And finally a very well regarded investment research site, that I think does a great job of creating compelling Call to Action copy.

Just sign up for a free newsletter and see what a great job they do of follow up and direct e-mail marketing. Not very pretty, but IMHO compelling.
I think you've got a big head start on a very effective marketing strategy and there are a lot of great examples of very simple direct web sites that are leveraged for excellent results with good copy.
Anyway, you may have your focus already really on target with your web marketing approach and the design will work just fine. It's some good things going for it already and no more than a few tweaks might be all you need. Don't get distracted from your strategy by worrying too much about the design.
Cheers,
James
