There is a whole big bunch of different software companies creating and developing software for video editing. VE have located a few of them (most of them perhaps.......) and made their homepage available to you through the provided links.
Pay them a visit and see what they offer and what they charge. You'll also discover that most of them have free try-outs, reviews, forums, help functions, manuals, plug-ins and much more. Most of them have other types of software as well, some to be used with the basic editing tools.
