Whew! There would be a LOT of work involved to properly finish that blade/knife. I can't speak for everybody, but do know that most professional Bladesmith/Knifemakers are reluctant to work on any knife they did not produce, and consider work of this type as "repair" work.... and in my shop, repair work starts at $65 per hour plus materials. Based on what I can see from the pic, there's a least a day+ of work there if it's done correctly. I don't know what you paid, or what you value it at, but I suspect the repair costs might be more than the cost/value of the knife.
