Hi there,
I developed one application which uses Stripe payment. I can help you to complete this project in 2 days. If you agree to do that, please send me the iOS source code and the account to login to the Stripe console, I will implement it and let you know when I have a build for testing. If you have any questions or concerns, please send me a message. I hope I can work with you on this project. Look forward to your response.
Regards,
Hoang.
