Hey, I'm Felix, a professional music producer, songwriter and pianist from Germany. I've studied music production, piano, keyboards and studio engineering for 3 years at the university of Münster, Germany. For the price, I can't rework the entire song, but I can send you the original song with the vocals filtered out. This method isn't perfect, as the vocal is pretty much perfectly gone, but there will be some minor phasing issues. If that is what you need, I'm looking forward to working with you!
