Cash Wedding Registry Plugin for Wordpres Site

I need to develop a plugin to create a WP Site focus on a Cash Wedding Registry. These are the requirements: 1-) Front end account registry (for the couple to create a wish list of products) 2-) Front end account manager (to add, modify and delete products for the wedding list) 3-) Every Wedding gift list is private (only with the password provide in the wedding invitation can access the wedding gift list) 4- Inside the account (of the couple) they can add, create and delete products (up load image), as many they want. The principal product fields are: price, picture, description. Multi-currency is needed. 5-) The user (Guest to the Wedding) can buy as many products as they want. 6- ) Advance Search for couples wedding or wish lists. (You can searh for weddings but to see the product list, you need to provide the password) the buyers users don’t need to have an account, just need to provide the password to see the Wedding list. 7-) The account users can add different types of events (Wedding, Baby Shower, Bachelor parties, etc.) to collect gifts of money, to each event. 8-) Plugin must be compatible with Paypal integration. We need to develop this plug in in less than a week. This is the website that we are using as reference to develop these plugin futures: [login to view URL]
