Build Groupon like website with admin panel - 5 pages only

Hi, I have got my template from themeforest its HTML with all html but i want to have a small admin panel where i can add deal products, images, information and categories and those changes comes in the frontend. I am not interested in a very detailed project but indeed its just 5 screen in total and there is no payment integration etc. I believe its a very small project for someone who is experienced enough. I want to get it done in just 4-5 days.
