Congratulations on your official marriage!
I'm not sure though if such a thing as a wedding planner exist in Ukraine, especially in Krivoy Rog or any other city ouside Kiev. Unfortunatelly. On the other hand, even if they had such a thing, it'd be a totally new type of service and I honestly don't think it'd be a great one

.
Good luck! In any case, I'm sure it'll be fun to take care of the wedding preparation!
Sorry I wasn't of any help.
