Transcribe a Piano Duet into a Solo Piece

This piece was originally written for four hands on one piano. A youtube performance of it is here: [login to view URL] The piece in question has already been notated down, but I would like this piece transcribed into a solo piece. It doesn't seem to be a very complicated piece so I would like the transcription to maintain as much of the original's color and weight as possible. It's ok if the resulting solo piece is hard, it just has to be reasonably possible. (Like hopefully a little easier than a Liszt piece but if it's harder than a Liszt piece then that's too difficult to achieve) I would like the Freelancer for this to have good classical piano training, but if you can get the job done well then I won't care about your background. I would want the sheet to be notated in something like Sibelius or Finale Notepad so I can hear the music before I complete the transaction. Obviously, I want the deliverables to be in a Sibelius or Finale file and a .pdf export. If you have any questions feel free to contact me.
