Price-range for dressing-up the frets on new MIM Jazz?

[perucci]

I've got a new MIM Jazz that I'm generally happy with, but I think the action could be improved. I've experimented with the neck relief and saddle-height to the point where I think I've pretty-much reached the limit of what is possible with a) the fretwork and b) my playing style.

Question: At a good music store (Washington Music Center: "Chucks" in my case), what price-range could I expect for someone to file the frets a bit, re-crowning as needed? There does not seem to be any obvious high or low frets; I simply seem to be reaching the limit of my mass-produced MIM's fretwork tolerance, ranging between 6/64 and 7/64. Note: I use DR Nickel Lo-riders, similar in design to the nickel Fender's it came with.
