Create Payment Code Stripe API

Hi everybody. Thanks for stopping by. What I need done is a simple thing with Stripe. I have a coded payment form. All I need you to do is 1) Process a payment for $x amount of dollars (I'll tell you later) 2) Then you need to process a one click upsell for $xxx (I'll tell you the amount later) I have instructions on how to do this, you just have to implement it! Let me know, thanks! My budget is $50-$100.
