Can anyone recommend a Chicago area HS Drone repair or parts seller?

So I badly landed my HS470 and there is no visible damage but the gimbal makes a buzzing sound and does not respond. The unit still flies and takes picture (with a stuck gimbal). At this rate If it can't be fixed inexpensively then I want to sell it for parts (cheaply). Thanks to the community out there!
