Build WordPress Donations app

I require a WordPress plugin to be developed allowing people to donate funds to a not for profit organisation. The plugin must allow the admin to configure gateways such as paypal with option to add extra gateways later, configure static amounts to donate, allow a custom amount field to allow people to add a custom donation amount. The plugin needs to record contact information (for mailouts) but must have a check box for the person making a donation to agree to email marketing (not compulsory), track total amounts donated, monthly amounts donated and amount donated to date on the admin page. Please contact for more information.
