Integrate Stripe API on Squarespace to Create Customer Token for Future Charging

Please read carefully and do not quote unless you are 100% certain you can do this job at the quoted price. I need to capture and create new customer Stripe tokens to manually charge my clients at the completion of a service. The amount charged will be dependant on the work and I do not want to charge the customer upfront... just want to capture their credit card details for future billing. I need a Freelancer to add a Stripe credit card capture at the bottom of the form on this page: [login to view URL] This needs to be engineered to create a Stripe customer token so I can charge customers with their consent at a later date, not at the point in time that they enter their credit card details and submit the form. The successful freelancer needs to be able to integrate the whole system seamlessly and teach me how to use Stripe's API to charge customers after the fact. Please, only submit considered bids with real (non copy and pasted) proposals. I will wait at least five hours before I award this project, so please take your time. DM me if you need any clarification.
