[WTH] Code to convert magnet links to torrent file

I need a Java code which can convert a magnet link to a .torrent file.

Here's a python script to do the same, though it doesn't work properly (The torrent file got created, but the download wouldn't start): https://github.com/danfolkes/Magnet2Torrent

My budget is minimal, PM me your quote and estimate time required (should be less then 3 days).
