Im wanting to develop a simple custom website to test a concept in the market. I will eventually embark on extensive development. I need a 5 page website, along with two separate dashboards (buyer/seller) - access by login, e-commerce facilities in the dashboards and a well configured blog. I need internal messaging and file sharing facilities. Would prefer to integrate google services and apps for the market test phase - working this into the dashboards. It will be a MVP, but it still needs to be near bug free and easy to navigate with sufficient UXD for an enjoyable experience.
