Saltydog, give some guide services a call. I think they might be willing to dispatch one of their trip guides on a day hike to meet you with a resupply.
It isn't legal with the F.S. for you to hire/pay a random person to do that (friends are ok, but the payment is the problem), but guides are licensed by the Forest Service, so their hiking in and out for pay carrying a resupply load would be ok. Try calling Kurt Wedberg's SMI in Bishop for starters.
If you call, please let us know what you find out.
