Hello

I am being asked as a contractor to estimate how long it would take to set up a working jot form registration form for about 30 classes.

I have absolutely no clue!

Can you give me a ballpark number of hours?

Thanks

If you want to create a form using JotForm, please check our guide and video on this link: https://www.jotform.com/help/2-How-to-Create-Your-First-Web-Form

Please provide more information about 30 classes. Do you want to create 30 different forms for 30 classes? 

We'll wait for your reply. Thank you.

It would be a single form which people would choose up to 8 different
classes of really likely 40 (not 30) offered. They would enter their
contact information and the payment would be passed through your form into
a cash handling system.
Thank you, Janet Kasper

We cannot provide an estimated time that would take to create a form, but based on the details you have provided, you may take just few hours. 

I would recommend you to start adding the fields where the users will enter their contact information, then you may work on the options you want to offer, you may use the basic fields such as single choice or multiple choice elements. 

You may take a look to the following guide where you will find more details about the different field types JotForm has: https://www.jotform.com/help/46-Quick-Overview-of-Form-Fields
