Personal Payment Gateway Developer

i need someone to code a personal gateway that will integrate STRIPE, TWILIO and will need to support Multi step workflows depending of the payment method (Interac card should be run as direct sale and any other VISA MASTERCARD AMEX DISCOVER JCB should preauhtorize and then give the option to CAPTURE, VOID or hold the payment. Generate a reciept. create Record Locator depending of the imput source. Pass troug the statement descriptor when captured. On stripe side, you need to be able to setup WEBHOOKS and API to integrate to our gateway. MYSQL to create the database where all transactions are stored. Integrate some extra payment method in a different workflow like : Canadian pre-authorized debits. The preauth capture sale and refund workflow should support virtual terminal imput, physical terminal imput (as choosen by the UI operator), a open hold section where any uncapture transaction should ce able to be voided and capture, a workflow to allow to initiate a canadian preauthorized debit, another page that will display status of preauthorized debit of the last 30 days and the ability to validate the pad with the two micro deposit from the customer. The twilio integation should allow an employee to call a number to obtain a preauthorization on a credit card that will show up on open hold page.
