C# Amazon Project Needs Updating

Need someone professional in C# with experience in doing Amazon Projects, if you don't meet these two requirements please do not bid. I'm looking for someone who can edit my existing source code, I need an Amazon login page + parameters changing, the old one I use to use in this project no longer works so it needs updating. I can point out where in the code it is and what needs changing. I can also provide you with an account for testing purposes on this project. I can only budget $30 for this project.
