In September you can purchase 25 silvers for about $125. The commercials(tribal/nontribal) will be begging to sell them to you at $5 a piece. Or about a dozen of your church members hit the rivers...they will be full of silvers.
Also many hatcheries are giving away surplus salmon that time of year. Sorry. I do give away a few salmon every year to some of the local elderly people just for the joy of seeing their smiles but in this case your asking a bit much
