A quastion to anyone who'd know this. Does any one know of a person who'd be able to properly clean the resharpen this baby? In southern United States??

Are you willing to wait the better part of a year? Anyway, given the cost of polishing, I would suggest first researching the value of this smith's work to make sure it would be worth the investment of a professional polish... Here's one that sold in December, signed Yoshiomi and in koshirae:

This singular example could be a statistical outlier, but from my own (albeit limited) experience, for each nihonto I have owned that is worth the cost of a polish, I have owned at least one that was not.

FWIW, I have had success with Noxon 7. It is a polishing agent, but an individual known to me - who has bought and sold more nihonto than I will ever see - swears by the stuff as the only metal polish that he considers to be safe for nihonto. Gentle-to-moderate pressure* with a soft cloth... I've been able to remove a fair amount of oxidation similar to what appears on your example, and it will enhance the visibility of the hamon assuming there is one.

Either way, a nice gendaito...
