Well, what kind of style are you looking at for the Slider/Snow Mountain remixes?
Also, would you accept a WIP of the song itself as an audition? Because right now, I'm just getting my feet wet with remixing and, while I think I have a lot of worthwhile ideas in my head, my portfolio is nonexistent and I would probably end up collaborating with someone more experienced to help me get these ideas into fruition (provided that someone is willing - I know you said that you were willing to offer acoustic guitar services, right?)
I'm sure this isn't instilling much confidence in you, but I really feel inspired with this and if I could get some help and advice, I think I could work it to a point where it's presentable despite by limited mixing ability.
I guess I'm just spewing random thoughts more than anything right now, but like I said I feel like I've got the inspiration and I really want to help out with this project in any way possible
