Washington State and CA have some of the highest union rates. In WA employers usually want you to have at least 10-15 yrs experience. San Francisco area is moderately busy, but expensive to live.
Southern CA is pretty crappy work wise, lotta low $$ stuff.
TORCH (New Orleans) is always hiring, they have work several states. The place is a tad on the odd side, but never heard of anyone getting ripped off. Not a lotta bucks down south though, need to head north for that. Canada needs HSE certs, but an American working there would have to be under the table anyway. Been known to happen.

There's always seafood harvesting. You like uni?
Spearfishing commercially in FL can pay OK, and bug season is coming up. You'll need to buy at least 1 trap permit to harvest by hand (I think).
If you're in the right places, 1000 lbs/day isn't unreasonable, though they don't stay in the clusters much past August (opening month).
Guess where I'll be in August...
