We'll take this conversation to PMs if you're really interested, but I can set up the exploit on a memory card at no cost except for shipping. It's very easy to do, but you have to be able to boot backups/burnt discs to install it. But once it's on, there's no limit to what you can do.
What I'm offering is to set up a memory card to automatically boot homebrew software like HDLoader and ULaunchELF. The only way you can do it yourself is with a modchip or Swap Magic, but I can do it for you.
