موقع دفع ووسيط

I am looking for a website that acts as a payment intermediary between a bank and a merchant. The accepted payment methods will be credit/debit cards, PayPal, and bank transfer. The website will be used for a program that supports citizens with the value of food purchases, and the cost will be deducted from their upcoming purchases. The program will sell physical goods, and refunds will be available in the form of a discount on the next purchase. The refund amount will not exceed 10%.

Ideal skills and experience for this project include:
- Experience in payment gateway integration
- Knowledge of e-commerce website development
- Understanding of refund and return policies
- Knowledge of food industry and food purchasing programs
