Programming for Non-Profit Site

We have a static site designed and built for a non-profit organization. We are in phase 2 where we need to add all the desired programming. We were thinking of using Joomla, but are open to suggestions. [ ][1]Specific programming needed includes:? * Sponsor a Participant Page * Back End View (collecting information from donors and being able to retreive this data is absolutely critical for? the organization from a recordkeeping and compliance standpoint) * Auto Response (to donor and staff) * Donate in a runners name * General Donations page? (Use PayPal for donations with an automatic email that is sent to donors (Certificate of Acknowledgment) and we will want to personalize the email with the name of the donor and the amount donated) * Fundraising Tips / Spread the Word page? (ability to edit text and photos) * History of the Organization Page (ability to upload pictures of officers and directors) * My Personal Page for those that have registered when they log in (see site example for functionality) * Store page (E-Commerce) with PayPal payments * Individual or group registration? page where runners or volunteers will sign an electronic waiver and an auto response will go out to donor and staff.
