Automatic signup, reminders and billing

We are building a website selling online services. New customers currently fill in a form to sign up to the services they desire. This form currently submits to our CRM, which creates a new customer record. We would like the info from the form to also automaticlaly perform the following: - Send the user to our payment gateway where they can pay a deposit based on the services they ordered (API) - Submit the information to our suppliers as a batch file to begin the process of connecting the customer (csv) - Add the customers details to our billing system (csv) Bonus points: When we receive emails from our suppliers alerting us as to status changes in the customers order (i.e. setup has been delayed, setup completed etc) we would like some sort of macro that reads these emails and alerts the customer on our behalf. We have the CRM, the billing system (mostly), the signup form and the payment gateway/merchant account all more or less sorted. We just need someone to help us plug them all together and have as much of the signup process automated as possible.
