Here's a link with a bunch of choices that might work for you

In particular take a look at:

Master Blaster
Foam Diver Head
Sailfish fly heads

You can also make Crease flies any size, or punch out popper bodies from a foam block (or abandoned lobster/crab trap float idf you're anywhere near a coast) with a copper pipe (sharpen edges a little with a file to cut through foam, use a dowel or coat hanger to push out foam plug)

good luck,
