Need a Few Contact Forms Created for Shopify Store

I am looking to have a few contact forms created. One of my competitors https://sheepdogmics.com has multiple. I am not sure if they are using an app or coding. I would like to know what they are using and use the same:
https://sheepdogmics.com/pages/contact-us
https://sheepdogmics.com/pages/contact-information
https://sheepdogmics.com/pages/warranty-support

Above is just sample pages for reference.

I will need pages created and be able to make adjustments.
