Build me a web interface

Job ID: 33750575

Budget: $250 – $750 USD

I am looking for a competent person to create a web interface that will propose to replace a bitcoin transaction by another one.
This is a simple function integrated to the bitcoin protocol.
The goal is to create a web solution so that the user can:
- Specify the amount he would like to send to an address X
- Specify the Y address to which the second transaction will be sent
- Have a button at his disposal to proceed to the sending of each transaction

And finally, a percentage that will be credited to me each time the user replaces his first transaction.
