Help with CRM

I need to collect payment details when user creates account on my site and the card needs to be authorized at that point. IT will be stored on Braintree/a paypal company. I have all instructions for all of this along with sample code. This is going on a uber type page. So here are the different codes I need. 1. Ask customer for Billing info upon username creation and Pre authorize card at this point. if card not authorized or valid, do not allow the creation of account 2. When customer presses the button to request a ride the card is then Pre authorized again. If authorized, it allows the order to go through. 3. When driver presses end trip button, the customer is then prompted with a box that says Would you like to tip your driver? If the customer presses yes, let them enter an amount. it takes the reading from my drivers device which displays the mileage and adds $3.00 for base fare rate. mileage is 1.25 per mile. + any tip amount entered Then I need a receipt created that has the following and automatically emailed to the customer iShuttleU Services receipt The date The time in central standard time Mileas- 2 @ 1.25/mil = $2.50 Base Fare- 3.00 Tip amount Total-
