Build an Online Store for my site

Our greatest need is that of a small system administrator I am no longer able to manage my system to Best Practice Standards, . Once the system is locked down, secure and running smooth and dependably,....I have a primary domain and several others most run offline. But I am ready to monertarize [login to view URL] . We have built a number of options in website form and again we would like to monterize the best of it. Price is important, but we are very loyal clients and hope for a better future.
