How do you polish a concrete slab to be a finished interior concrete floor?

We have in-floor radiant heating. The slab is the bottom floor of our home, which will be garage and apartment. We are interested in finishing the apartment floor to be a light grey concrete floor that looks nice. The concrete was poured 8 months ago, and we are noticing some divots. We live on a remote island with no specific concrete flooring experts, and I'm having trouble locating a large diamond grinder.
Are the divots in the concrete the reason for you wanting a diamond grinder? If the slab is currently polished, then I would think in your case, repairing the divots would be a much easier way to get to a finished floor you are happy with rather than grinding the entire tops surface.
Filling divots in a slab on grade home can be a simple matter of using self-leveling concrete, and you can then use an angle grinder with a buffing pad rather than trying to find a diamond grinder, which seems to be quite an ordeal for you in your location.
