Recreate a PayPal Payment Form using updated PayPal API and C#

We have an old project using a very old version of PayPal Gateway/Payflow to handle a payment form. We simply need someone to recreate the form using the latest PayPal API (downloaded through Nuget). This is a fully integrated payment form using the PayPal API to process credit card transactions, written in C# and using ASP.Net webforms. I will provide screenshots and some of the current code to use as a guide.

All we need is a new version of this form with a button that we can click to process the credit card transaction--collect the card and billing info and submit it to PayPal while retrieving the response and displaying the final payment status. You can create your own form.

Please let us know your experience with PayPal payments integration in you proposal. Proposals that do not include this will be ignored. You will need your own PayPal Sandbox account to test with.

I am including some screenshots for you to review, including some of our existing PayPal code that needs to be rewritten.

Please note:
The code must be TLS 1.2 compliant.

And we are ONLY looking for someone who already has PayPal integration experience. This should be a very quick project for someone who's already done it once.

Skills: .NET, ASP, ASP.NET, C# Programming, PayPal API
