Hello, I am needing a mobile friendly website built that multiple users "advertisers & businesses"(1-100) can have their individual back office to update and edit their info. and a pic. of their business. They would also need to be able to put their business in a category such as entertainment, food, family etc. All the posted content will need to be able to be viewed by clients on a mobile device(smart phone mainly) when they access the website to view advertisers and businesses info.
