egg protein powder as mentioned before is probably your best bet, highly bioavailable, and used to be the standard for which protein was judged. The GEMMA protein (pea) also looks promising, but it's still a veggie and lacks the "oomph" of a dairy or animal source... i have no evidence for my reasoning, just a gut feeling. Wheat Protein is now carried by some reputable companies, but that also has the veggie issue, and gluten intolerance is very common so you may want to be careful with that.
As far as speed is concerned, I would go with some EAAs or BCAAs and add some Glutamine or Glutamine Peptides to go with that. If you can get a good amount of that pre, during, post-workout then you are covering your most important protein requirements of the day IMO, since speed is of the essence during that critical time. If you have the $, go ahead and use that first thing in the morning with a quicker digesting carb too.
aside from workout times, and morning, going with the other protein sources should be perfectly fine, including whole food sources, which are the best IMO.
