application needed to send dm to nike accounts instantly

When a new shoe release is announced Nike will tweet a hashtag. the user must send a dm to the nikeseattle account with name, size, and the hashtag. i need an application that will do this automatically...preferably for multiple twitter accounts to get as many reservations as possible. another project that is similar would be when @Nikeonline sends a link to buy an item. they often sell out in seconds. there are apps out there made to automatically buy the product once the link is sent...instantly. references: [login to view URL] [login to view URL]
