If you are handy with a knife (meaning can handle a stiffer blade comfortably) and can use a stone to keep an edge, pick up a couple Dexter Russell 8" Wide Boning Knife 2150 1378 with the wood handles and call it a career. They run about $25 each or so.
It's a staple of the northeast ground fishery (cod, haddock, pollock) since I was a kid working on a fishing boat in the summers and still used now. My son uses the same model when he worked a few summers on the party boats recently. Simple design, sharpens to a razor since it's a high-carbon steel blade, you can sharpen repeatedly over the years and does EVERYTHING you want it to do with the right person using it. Filet, skin, chop, steak a fish...
Since it's a carbon-steel blade, if you use in saltwater, take care to wash the blade thoroughly and put a wipe of veg/olive oil along the blade. Just wipe it prior to next use. Also helps to oil the handle since it's wood and prevents cracking. Pick up two for around $50 and you won't need to worry again. I say two in the event you lose one
