I suspect it would cost about as much as the knife did to pay someone to polish that - and it's a job you can do yourself.
get a pack of multi-grit wet/dry sandpaper from the auto parts store and a scrap of wood.
start at a "low" grit like 320 working parallel to the edge and sand until the machining marks start to thin out.
go up a grit (400) and sand perpendicular to the edge until you have sanded out all the scratches from the previous.
go up a grit and sand parallel, etc....
above 800 grit, it should start looking shiny
1000-1200 and you should be getting good reflections.
if that sounds like too much work and you have access to a random orbit sander, you can use it to clean up the tooling marks (again, 320 & 400 grit) - and it will leave a texture similar to a stonewash finish. if you use a scotch brite pad, you end up at a satin finish.
follow up with a buffing pad and flitz or peek to polish the knife.
hope this helps.
