How can I send custom wattage calculator data via email?

Hi,

I have a custom-made wattage calculator that lets the customer choose the options for multiple rooms and download the records in pdf format, I want all that data to be sent from the Shopify admin email to the customer’s email in a downloadable pdf attachment along with personalized email template.

Here is the link to the custom calculator,
