How much to get frets sticking out the side of a neck filed down.

[wasteofo2]

I've got a bass which has frets that are sticking out the side of the neck just a tiny tiny tiny bit (far less than 1 mm). The frets are made of stainless steel, and it's pretty uniform throughout the neck. I was wondering how much I could expect a repair guy to charge me to file this down, if any of you happened to know.

Thanks alot,
Jacob
