Payment Page embedded into HTLM Form

We just want a form made with a credit card details payment at the end of the form.
That is it. The form in web link access is here - http://www.jotformeu.com/cash2bank/estavisa

Now I do have this form already in HTML in our website, but we need the card payments at the end of the form. The form provider we currently use is Jotform, there maybe a way to build the payment integration into the current form. If not we would need a brand new form done.

But this form must be HTML, as the site we are using is made on WIX.COM. Payment must be integrated into the form. And then once completed redirected to a particular page.

That is it

What we need is VISA/MASTERCARD integration into the form to allow a sale of service to be a seamless process.
