There is a long list of things we can do for you to help build what you want and need. The most important thing you will need to know is what you want to display and to have an idea of how you want it laid out. Along with those items you also need to have the information that you want to display, such as the wording of how you want to show off your products or why you think people are wanting to come to you instead of the competition. How about how you are going to complete the order (for example, you sell shoes, how do you ship and how long will it take).
People also like to know a little history in your business, to know you have been around and will continue to be around.
There are many different ways to display your content. SO much nowadays are going to image related, even though that is not the most friendliest for the search engines there still needs to be a happy medium so you can display your info AND get ranked on the search engines.
How about some training video's that may help you build your site and even to just understand it better.
