For what it is worth, I have seen a few things that you may want to consider:

1. Shouldn't the !doctype be at the very top of the code?
2. Next to free trial / demo / get started, above the categories, it looks like something is missing.
3. Although the right hand navigation is useful, it looks closely like a standard WordPress layout. I think you could have done more with it.
4. You have it set to display the default 10 articles per page. Once you scroll down past the calendar, the page looks lopsided. Even the footerbar is left justified.
5. Directory indexing is still possible.
6. After clicking the login, I received the following error - Secure Connection Failed tasks.nizex.com uses an invalid security certificate.
7. Under your interview link, I accidentally clicked on video window when the introduction started. This interrupted the video, with no way to restart it, even clicking the introduction link would not restart the video. I also noticed that there are no controls for the videos for introduction and talk payroll. Also the introduction and talk payroll videos do not overlap the side navigation while the other two do.
8. I did not see a physical address on the contact page.
9. You have plentiful information on what lizzy does, but I couldn't find any on the implementation of it. In one part of one of the videos it discussed monitoring phone calls. Does this have to hook into our phone system? What are the basic requirements?
10. You have a canonicalization issue.
11. Besides the url, what's the difference between the free trial, use demo and get started link as they all take you to the same page, which incidentally is the same as the contact sales and contact support page?
12. Your #top does not work on all pages.

Hope that helps.
