Fair enough. I just think you'll probably not find a trade person who'll take time out of more profitable jobs to do that.
Best to bang the job on checkatrade and see what comes back. Would imagine it's not much more than 1/2 a days work depending on kitchen size so £250 max?
It's really not difficult or expensive to do it yourself....
Rent or buy a random orbital sander and some 180 grit or higher paper. Buy some danish oil. Done.
