Build a Website

i have a site developed in yii framework integrated with paypal to charge users for signup/upgrade. we have changed our plans to monthly and yearly subscriptions now i am looking for some yii expert who have good experience in yii and payment methods and already have worked with recurring payments to add pay via credit card option and to charge users automatically on completion of their selected package(after a month or year). so if user create account and he select month, then he will be auto charged after one month. similarly if he created account for yearly package he will be auto charged after one year. an invoice should be sent to user's email when his payment gets charged. site details will be shared in PM
