ZSadds,
Your design, layout and usability are top notch. Most of the sites that I see wanting reviews on this forum have so many issues that it is hard to know where to begin. There were a couple small things I noticed but honestly the may only provide an incremental impact at best.

The site is consistent until you click on contact us, login or register. Then the color scheme changes and the top navigation is no longer present. Generally it is good to follow the same convention on every page unless it is a landing page with a specific purpose for not wanting people to navigate away. Even when you click home in the right column once on one of these pages, it does not take you back to the original pages. Not sure if this is by design or not.
Another thing was that the about us page doesn’t have a ton of content in general and does not contain any information about your company. Generally when people go to these pages they like to see something about the business (i.e. a brief synopsis of history, values, mission, etc.) A comprehensive about us section can help instill more trust in the site creator and business overall.

One thing on usability is your “email us” link as a method of contact. You have it configured to open the visitor’s default email client. While this is “ok” it is generally better to use a more universal method. Not all users will be using an email client in which case they will run into problems when trying to email you. You may want to reconsider how you have that configured (like just having a link to the contact form).
Other than those things I would say you are 98% on the way to having a highly professional site.

Also, I recommend this book a lot because it has some great common sense tips for web design and usability,

I don't have any complain about your design.
You should share your site information on social site and share some attractive offer .
I believe you'll get some order from there.

It's a nice looking theme however, it's very overused among hosting providers.

I thought it has a very nice, clean look. Very professional.

The Homepage is not bad but you should use the same design in the entire site. (example: Contact us, Register, etc)
