You've got 5 seconds to get your point across before your user clicks the back button. If you're lucky, after that 5 second scan, that user might click on the first handy link to see if it leads to any information. I gave your site the benefit of the doubt and scanned for 30 seconds and clicked 3 links. I never found anything that caught my eye enough to actually read on that homepage, and clicking links put me on two forms and a pricing chart. Now I'm back here with no idea of what you do.
There needs to be a 5 word chunk of text in 36 point font explaining what you do. Next, maybe a few big bullets explaining why this will help me solve a problem I actually have, and a call to action that I can click on to start solving it. At the most, you can put 7 distinct things on that homepage for my attention to land on. Choose them with care, because the average visitor to your site is going to be even more indifferent than me.
