What is pricing for multiple forms?

I am wanting to create a letter/form that a visitor can click on and be sent to any one of 50 different locations. Each letter may be slightly different for each location Each letter may need to go out to more than one email for that particular location. What would cost be. Do I need a form service to do this.

I am not sure if I understand your query correctly. Do you mean to send a notification to different email address based on the selection on your JotForm when it is submitted? If so, you may setup conditions on the form to send different email notification to different email address based on the selection by following the guide below:

You may send each notification to 10 recipients. If you need to add more recipients, you'll need to create another notification.

You may compare the current pricing plans available at our pricing page along with the features.
