I've been modifying my spare -3 boards to work in a game that requires a -1. The parts only cost about $10 USD here in the states - so they might cost a little more if you had to import them (I imagine you could find them in your country pretty easily.... but I don't know the suppliers that are 'preferred', so I cannot be sure.

I wrote a blog post about the process. I've done a half dozen boards or so now this way.

Now, if you can't solder, this isn't much help, I understand.... but you may know somebody who can help.
