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.

Hello there! I am a .NET developer having a very good experience in building web applications using C# and asp.net. I am readily available to work on the paypal API and to ensure that I have worked on paypal API I can tell you that I have recently worked on a Gym API that used Stripe and Paypal both in it as payment gateways there are some changes on the android part which our android developers are handling so we haven't uploaded them on the playstore yet. But I can share the One page design of the website where you can see some of the screenshots of the app. Please feel free to clarify the project and provide more details of the project over chat, Thank you!
