Welcome aboard!
Well, well, well… Where do I start 
I think you have a little too much “green in color” going on. You have green trees, various shades of green in the header graphic, the navbar menu on the left, and the green trees that can be seen through the ‘content’ area of the site. I’m saying all this to indicate there’s entirely to many distractions taking place on your website.
Based on the services you’ll be offering, people are likely coming to your site out of frustration for not knowing how to use their computers/software. Once they land here, they’ll likely be frustrated even more by having to spend their time trying to get their ‘bearings’ straight .
The text is extremely difficult to read with the background coming through… ideally, for newbies, sticking to the basics will take you far; and in this case, black text on a white background will make everyone’s lives easier.
Header Graphic: Too much blank space there. That is a very valuable piece of real estate and you should use it to help get your point across. When a person lands on your site, your primary goal should be trying to pick-up on the dialog that’s already taking place in their heads. You want these visitors to know immediately that they’ve landed on the right website and that you’re the guy that can help them. “Green In Color” says absolutely nothing about what you provide and it's a great chance many will bounce after only seeing that portion of your site as it is now.
Content – you’re lacking this big time. Your post on this forum gives me a better idea of what you’re trying to promote than your website does. In order for people to purchase from you, you must provide them with enough information so they’re able to make an informed decision. Your website doesn't do that!
I suggest you start from scratch and work your way through again... or hire a professional to do it for you.
