We are looking for a magento plugin that will allow customers to create a subscription of their own fo 6 products (any) from our shop. They can then pick how often these are sent out, they can ammend the subscription through their account and they can also pause the subscprition if they go on holiday. The admin will also need to be able to view all subscriptions, get notified of upcoming subscriptions that need to be sent out etc. This should all be on a sepeare page on the site, and not affect the way in which customers buy items individually.
