Seeking percussionist w/ vibraphone & marimba savvy

I've been waiting for somebody (best would be a percussionist) to make any supportive observations about a new composition "Marimba & Vibraphone Mini Concerto) on the .COM Pro channel, but nobody has expressed interest. I'd rather not upload the score, then find somebody says, "hey, here's what you should have known /fixed with the Vbra & Mrba parts". I'll fax any helpful person a 4-pack of wine coolers. Appreciated.
