Just finished a small concrete job so it's fresh in my mind. Although there are more honing steps involved than for marble, as opposed to say honing a 10 sf area for 4 minutes, you can make one (depends) or two passes to get a good cut. We got down to about 1hr-1hr 15 min for 420 sf after the first couple of cuts. The grinding part below 100 grit metal can be slow if you don't have much horsepower. 
Also for a small job you may need to go with a small 17" machine on  110 power. We tried our 220 Klindex and it just blew fuses. At the low grits the machine may heat up often but once the first one or two cuts are done it will go much faster. Going all wet will help with cooling the machine. You can use 5 x to really enhance the shine and you don't need much powder or time per section. Alternatively I tried Spinergy pads from 1500 to 11000 grit and they also did a creditable job. Only 15 -30 seconds needed per pad (5 pads) wet. Then go over with the 11000 grit pad dry. 
Edges and corners will really add to time, so calculate in (about 2 min per Grit for 15 feet.). One reason the commercial jobs are priced so low is that they us much larger and more powerful machines that don't work well in small residences. 
Another thing- the job creates a giant mess, so I would get two people on the job, one to hone and one to pick up the slurry. If you feel comfortable going dry in the higher grits, one man can do this, but you need a decent leak proof connection between the floor machine and dry Vac to pick up the dust. My Klindex has this but the 110 stonemedic doesn't. 
Anyway, some thoughts on the matter.

I agree guys should charge what works for them. Depending on equipment used, CP work is more expensive. Also sometimes edges are avoided and others blend them in. This is a big difference in labor.

 John.. that would be our rates for commercial work. 

Residential is obviously much smaller. Dyes and sealers are often applied as well. Also, Florida is a different market due to the economy and there are more diamond polishers there than anywhere. I cater to high end residential in NYC, however I believe we all should get top $ for this work, especially for removing glue.

Tony,
Don't worry about what others charge. You need to figure out your cost and profit margin.

Your going to have to cut it deep after the glue is removed because the adhesive is going to leech into the concrete. Plan on starting with 16 or 30 grit metals and working your way to 220 resin to densify and proceeding to the finish their looking for. Don't know the sq footage or machines your using but I wouldn't  go below $4.50 per sq ft and would probably ask for $6.00 including adhesive removal. If you can't make money it's not worth doing.

Hi Everyone,

 

I am doing an estimate on an old concrete floor that had carpet glued down to it.  They want it polished.  I’m interested in finding out what price range most of you charge. 

 

Thanks for any and all input.
