SEO for Ecommerce Site

I am starting up an eCommerce business that will primarily be selling Panoramic Photography and Virtual Tour related Software and Hardware from Europe in the U.S. I have a designer and programmer working on the website now and should be ready no later than mid June. My focus will be the hardware and package the software as a bundle as most software is available for purchase from the developers directly. My main suppliers will be [login to view URL] which sells software and hardware and [login to view URL] which sells hardware and Benro tripods and accessories. I will seek other suppliers but these are my main two at the moment. . Competitor websites are: - [login to view URL] which is the only business that sells Kolor products in the US - [login to view URL] which produces and sells their own panoramic tripod heads - [login to view URL] which produces and sells motorized panoramic tripod mounts and their product is the main competition because they have the majority of the market for motorized tripod mounts in the U.S. - Really Right Stuff which makes all kinds of photography tripod accessories and not a big competitor There are other competitors but they are smaller and cheaper. We can discuss them once I find the right person for the job. I want someone who is motivated, knowledgable, and experience in Ecommerce for new and emerging markets
