Use the FREE option when creating a website in Weebly and Wix. If it's asking you to pay, you probly selected the wrong option.
In Weebly, when you create a website and it takes you to the editing page, choose the first option:
Click the CONTINUE button.
Next, click the PUBLISH button. Location: top right. It's blue.
Your website should now be published, for free.
Now if you send someone the link to your website, (in this example, it's: http://mychicanowebsiteexample.weebly.com) they should be able to access it without having to use your personal username & password.
