Wordpress ninja forms, conditional logic. Stripe integration.

We are running an event where we are preselling tickets. We need a ninja form with stipe integration to collect the payment and the user information. We need conditional logic implemented to handle when the user wants to buy 2 or more tickets. This means if the user buys two tickets we need to collect the first name last Name company name email address and a few other fields for each user. Once they fill in that information we will have a calculated field that will show the total cost for the tickets selected. Please have experience in using and ninja forms and conditional logic with calculated fields. Once they complete the information they will be directed to pay the calculated amount via stripe payment intagration. I need this form completed within the day and embedded on our word press site. Please provide examples of similar work you have done. Here is the link for ninja.
