If just a bit rough - normal floated or power trowel finished or maybe broom finished but otherwise adequately planar and level, typically around $2-3/SF for power grinding (carbide or diamond grinder which looks like a floor polisher on steroids) will give you a surface you can then paint, seal, put an epoxy or polyurea or similar coating on, or polish very smooth and cover with a clear finish. Or just cover with carpet or whatever overlay flooring product.


If you need a levelling overlay, then instead of grinding the surface you would level it for typically about $3-5/SF for an overlay on a not too sloping floor (say not more than an inch or two out of level) - though of course depending on how out of level the concrete is, you will lose a bit of headroom - typically 1/8-1/4" minimum at the existing high point as you bring the rest of it up to level.


Going that extra step to a finished concrete floor surface (stained polished concrete or a epoxy or urethane coating) is typically another $2-3 to about $5-7/SF depending on finish chosen, or going with a higher-end pattern stained or the more resistant poly-urea or polyaspartic coatings more like $5-10/SF additional after the initial grinding. And on up from there for custom patterns, in-floor designs, logos, etc - can be as much as about $50-100/SF for intricate designs and patterns, which are really "artwork" rather than "floor finishing".
