Automate Human Behavior on Web Browser to automatically set rDNS on Servers

Watch this Quick Video which Explains what I need: [login to view URL] We Setup and Configure a lot of Servers from lots of different Hosting Providers, and each one has a completely different Control Panel for setting the Reverse DNS for Domains hosted on the Servers. So, we need you to create a Program that can automatically update the rDNS by simulating the Mouse and Keyboard Actions on the Web Browser so we can do it all in 1 Minute instead of 30 Minutes, and avoid the risk of Human Errors. IMPORTANT: Your Program must have a REST API that we can send Requests to and receive Responses back to us, and the Program and API must be hosted in a Linux Server. Please Bid a Flat Fee for Creating ONE Program, for the 1st Hosting Provider, then we can negotiate for additional Hosting Providers. This is a Web Automation Project - I think that's the Keyword.
