Hi,
When I saw this ad I actually got excited, because many years ago I made an Ultimate Team autobuyer in C#, which was a really fun project.
I can update the toolkit and make the program for you. I have used the library you want updated previously as well, so it will be fairly straight forward for me. I can work on it around the clock and have it completed for you within 10 days.
Message me so we can discuss further details, thanks.
