I've been trying to find anyone that can do sidewalk grinding to remove trip hazards, but no luck so far with the ones I've found via Google in the past week. Can anyone recommend a contractor that does sidewalk grinding. I'm looking for someone that does work like this:

(Note: already contacted that company, they don't have anyone in the Philly area)

I've seen lots of sidewalks fixed like this in NYC, but not in Philly so far.
