Recharge Website & Application

Hello! I'm looking to get a recharge website created and have some questions that I need help with. I plan to offer mobile, dth, and playstore recharges on the website and it will be a standalone website, separate from any existing website. As for payment methods, I plan to accept credit/debit cards and UPI . I'm looking for a freelancer who can help me create a great website that runs smoothly and on time. Thank you for your time and I look forward to hearing from you soon.
