You don't need anyone but Doug. He has a long history w/ NEC and knows the machines inside and out.
In fact, I noticed your reference to ISF. Consider that it isn't ISF you want but someone who understands the in's and outs of properly setting up an NEC. They are very different from most projectors and take an experienced hand to be done properly.
William Phelps is in California. He just finished my Sony and it's staggeringly good looking (PJ, not William). I have no experience with Doug and I'm sure he's excellent but I can sure vouch for William!
