Auto-Responder Drip Message

We have an existing website with an existing auto-responder. The current auto responder is called [login to view URL] and will fire out one message. We want to expand this script to fire out 3 message all at different times. I can post the [login to view URL] file for you to review if needed. We need to add three drip emails to the website. When someone visits the website and submits their email on Step2 they are automatically subscribed to the three drip emails. The emails will be sent out as follows: Email 1 – in 24 hours from the time they completed step 2 Email 2 – in 48 hours from the time they completed step 2 Email 3 – in 72 hours from the time they completed step 2 When the person binds their link to the funnel they are automatically unsubscribed from the drip auto responders. The three auto responders have already been created and are located within the directory. This should be a simple process. We had a deadline that was already missed so the total amount of the project budget it $125-150.
