How to make form URL shorter and more customized?

Is there an inexpensive/free way to make a URL that is short and makes sense? I did this form for my church, and would like to have a short URL to give to families to register for VBS, that is not necessarily connected with my other business addresses.

You could check this guide on how to make a custom URL for your form: http://www.jotform.com/help/261-How-to-create-a-Custom-URL-of-a-form. But please do take note that your username will be attached on that link.

You might also be interested in changing the domain name of your form URL, if that's the case, you can check this guide: http://www.jotform.com/help/144-How-to-use-Custom-Domains-with-Jotform.

I hope that helps.
