AWS Lambda, Golang, HTML Contact Form ($30)

I need a 'Contact US' form' API using lambda function and Golang code. My website will have a static page with contact form. I need code for 'submit' button that will call lambda function and send filled form to my email. I will need Lambda-Golang code to host on AWS Lambda. Also, instructions to setup API gateway that will trigger lambda function when request is received. Contact form is attached that you can modify as needed. The contact form page can be moved to AWS Lambda if needed, where my external domain can call it.
