Implementation of a marketing automation system

I am looking for a person to implement a marketing automation system in the logistics industry.

We are currently acquiring customer email addresses via forms on the website.

What we want:

- automate the sending of emails with invitations to events

- automate the sending of e-mails with offers

- plug in all forms on the site

The system must have a calculation of how much time a potential customer spent on the site and on a particular product and then send him an email based on that.

The products on the site are more than a dozen.

I am asking for offers with a specific amount for implementing the system.

The next steps I would like to do is to implement several automation campaigns and I ask for such a quote separately in the message.

Thank you and Best Regards.
