I want to add a Contact Form to a website. There are 4 options in the Online Content Catalogue:

Google Forms:- this entails the contact having a Google account. Not everyone has or wants a Google account.

JotForm:- This has 3 paying options and 1 very limiting free option

WuFoo: This has 4 paying options and 1 even more limiting free option

Form2Go:- This widget changes to Form2Pay with a free trial offer

How do I install a simple, free, customisable contact form to my page?
