Of course you know this ride you're planning has been discussed for weeks here on this forum and I'll only repeat the best advice I've heard yet: just do Burro/Hazard/Kokopeli/UPS/LPS, then bail down to a waiting vehicle at the tanks on Salt Flats Rd. Save the entire Burro to 128 ride for late September.
What I'm sayin' is you're going to have more luck finding someone who will do the above shortened version than the Full Monty which means getting down to 128 in 105 degrees after a long hard ride. Heck, even I would do the shortened version in July. If you've never done Porc and you're not going to be back ever again to Moab, the next day you could do just Porc as a shuttle starting at 5 am. That way you'll still get down to 128 in 105 degrees but you won't be so beat up by the time you have that 4 mile hot ride back into town.
