Email Game Engine

I'm developing a game to be played through email/text message and am looking for a developer to build the engine. Functional Requirements: -Send emails -Trigger autoresponders based on incoming emails -Establish time delays for autoresponders. Such as the system sending the follow up email after X hours or not until the next day -Read/Analyze text in incoming for specific keywords -Send autoresponders based on the incoming text. For example if the email had the name "Veronica Lake" in it to send one message and if it didn't have that name to send something else. -Keep track of where the user is series of emails. Because it's a game the system needs to know where the user is in the story line. Using the name "Veronica Lake" in Act 2 shouldn't trigger an email from Act 1. -Have an interface manage these story lines and autoresponders. Here is a flow chart of how the series of messages would flow as an example. Focus on the Act 1 tab as it's the simplest and most clearly labeled. The uploaded files are the example emails that would be sent for each of the emails shown in the diagram. [login to view URL] Workflow: Here's a short narrative to hopefully better illustrate. 1. User registers with their email address 2. User receives an initial email with an attachment 3. User gets a second email 2 hours after receiving the first, from a different character 4. User sends an email containing a specific keyword "Veronica Lake" 5. User receives an email saying that they succeeded. 6. Had the user sent an email not containing that keyword they would have received an email prompting them to try again. There are other aspects of the system that I haven't really mapped out. For example, it will need an ecomm form to collect payments. Hopefully I did an ok job of explaining the overall concept. I'm very open to feedback to simplify the game as I know sometimes adding in one innocuous sentence can add entire layers of complexity. My goal is to have a minimally viable product that would allow me to create the email flows.
