I have received some advice on my post... Here are some more details about the trip:
The launch date is February 15th, 24 days on the river, pulling out at Pearce Ferry. We are going with Moenkopi Riverworks for our outfitter. As of right now, the trip cost is ~$1,2500 per person (that includes gear, food and a place to stay before and after the trip, but it does not include a dry suit or the $110 NPS permit). And we are always looking for ways to lower the cost further!
We are aiming to fill the 16 person permit- 7 of those being capable oarsmen for the 6 boats (plus an extra rower for backup). We currently have one dory, one personal 18' raft, and four rental 18' rafts (which is what potential oarsmen/women would be rowing, unless you have a raft of comparable size to an 18'er for gear storage on a winter trip). The group is young and old, guys and gals- all very competent in the outdoors but not necessarily experienced boating. I would characterize the group as a diversely interested, high functioning group of fun people. I am in my 20's and about a quarter of the group consists of my fellow friends and guides from the outdoors program at UCLA. We've even got a native american flute player for morning wake ups! Definitely placing an emphasis on getting in a lot of side hikes (24 days should be at least three layover days, even in February), fun around food and the campfire, and getting to know the history of the canyon. Not a heavy drinking group, but also not a dry group.
Looking for two more rowers!
