Automatic Texting App

I need an app designed that will automatically send scheduled text messages and multiple attachments (images, pics, video) on a specific date and time. The messages have to come from the senders ACTUAL CELL NUMBER, Not From A Third Party Number. For example, when the person on the receiving end gets the text, it comes from the senders actual cell number as if receiving a normal text message from that persons cell phone (not an unknown 3rd party number). The app needs to be able to EASILY select individual contacts to send a scheduled text to, and also be able to EASILY create a group to send multiple contacts a scheduled text to. The app needs to be able to accomplish recurring events (ex: be able to set once and forget) to individual contacts or group contacts, such as holidays that occur each year, birthdays, etc. The contacts and created groups need to be easily accessible when creating a text. The user experience needs to be easy, concise and extremely user friendly. The graphic design needs to be appealing and inviting to the eye.
