Design is nice but there is just too much product oriented info without clear call to action where user should go next. And with product oriented I mean there is no visitor segmentation. Such product listing should be part of conversion process not main page. On main page you should offer few basic options for small, small to medium or medium business with clear pricing and timeframe info. All these product details can be attached later as upsale process
This slideshow here is confusing. I'm guessing the users control the slides on the translucent arrows on left and right, but I'm not understanding the second set of arrows in the blue bar, or what the bubbles mean. Are those the actual slides? If so, think about centering these controls on the page.
You've got way too many modules here competing for prominence. Think about maybe decreasing these to three each (in a row). Give the user a bit to go on, but don't provide them everything like this on the homepage. Too much to focus on.
I would remove this video, but check and see how many people are actually viewing it. The primary action they need to take on this page is to send you a message. I would doubt that people would view this video after (or before) they've done that.
See my notes -- I think there's too much here on the homepage which may account for the high bounce rate you're talking about. Try moving your CTA at the bottom of the page up near the top and cull some of the info to provide a more streamlined content experience.
I think the way forward should be "less is more". Try to come up with much shorter answers to the basic questions such as "What do we offer?" and "Why should you choose us?". The answers should be clear to the website visitor in under a minute.
