Edits made to a plugin processing payments via stripe

Description

I need help with some edits to the plugin GeoDirectory. I'd love to get your thoughts / opinions and quotes if possible.
So I've added a load of extra fields to the booking form and have them all pulling through okay.
What I do need however, is to add some card details on the front and have them send into Stripe. As they are placing a booking, but we don't want to bill them if it doesn't get accepted. The plugin already is setup to take bookings and process payments in stripe so hopefully a simple job for someone that's done this before.
Anyway see the page with the form on it here:https://4cornerscamping.com/places/test-home-ml/
Could you give me a quote on adding the card details field and getting it to link into our stripe?
Also seperate quote.
We have 3 different place types. We only need things like driving licence fields on the Motorhomes. And not campsites.
Could we use a different form based on category? And could you give me a quote for that as well please? Like if this category use this form if this category use that form. If that makes sense?
Thank you,Michael
