Website Design for NON-Profit organisation

We are looking for the design of a not for profit website. We require the same functionality as the following: [login to view URL] [login to view URL] The ability to take sponsorship/donations and backend to an onlice banking system. We also need a backend database where a user can add their details and upload a word or .pdf document and then once we review the document, we would then have the ability to publish this, with a brief on the company and a link to the document. We would also need to have the ability to have the database create the same type of popup as the green tick at the bottom of the [login to view URL] website We need the ability to have a searchable database where a user can search for a company under a category or in a search field. This should give you an indication as to what we require. Please note we have a very tight time frame on this
