I go up every summer usually during the August time frame to target silvers and bows. The Alagnak is a great river to do on your own. I've done it twice and the float is strait forward and great fishing. We used Branch River Air out of King Salmon. I don't recommend thier gear, but they fly just fine. If you want to consider flying out of Bethel to fish the Goodnews, Kanektok or Togiak river, or maybe some rivers that flow in to the Kuskokwim system, I can pass along an outfitter and air service to you. Leave your email, and I can get in touch with you directly with more detail info.
