creating redirect URL from a webform

Hi - I'm wondering how to create a form on a website that can create a redirect URL based on the information that was submitted.
The point in reference is a reservation form - if the date is entered, number of rooms, etc, I need those entered values to help create the url.
I'm using Ninja Forms, and their webhooks add-on seems to do this, but it just sends the information to the server - it doesn't redirect the visitor to the site. Can anyone tell me a simple way of doing this? (I'm no developer, and Ninja Support offers no help, despite 3 emails to them). Or if I need to hire to get this done, do you have any recommendations as to who could do this for me?
