Obviously your specific circumstances affects the cost greatly - but to give a pretty much off-the-cuff order of magnitude number:

1) If you mean a commercial kitchen - restaurant or hotel kitchen or such - depending on size and how many floors the flue passes through, probably not less than $1000-1500 range for a single-story exhaust flue to many thousands if in a high-rise - like a hotel restaurant where one might go 10-20 floors to exit at the roof. The problem is generally if it is going out of service (as opposed to just being replaced with a new exhaust hood) the flue ducting commonly has to have firestops put back in at every floor - meaning ripping the flue out, then installing fireproof firestops floor by floor and in the roof - gets pricey REAL quick. Was involved in one in a major hotel - about 22 stories high as I recall with kitchen on ground floor, after a grease fire which spread from the exhaust system to the hotel floors caused the fire marshall to require them to remove that and replace it with a direct-vent system directly to the outside - ran over $25,000 all told, NOT including the fire damage repairs to the hotel.

If you meant remove the exhaust hood ONLY - preparatory to a whole-kitchen rehab say (with replacement hood to be put in as part of the rehab) probably around $500-1500 range depending on size, including disposal. Generally a two-man job at least because of the size and weight of the hood and blower motor(s).

2) if you mean a commercial-size hood installed in a house (so maybe 4-6 feet wide) probably about $300-600 depending on size and access issues. Again, if being totally removed (no replacement hood going in, be it commercial or residential sized) then may be required by code but either way to avoid condensation and grease accumulation issues, at least in areas with cold weather, the ducting should be removed from hood to roof also and the roof penetration patched - which might be another $500-600 very rough ballpark cost - probably around a third in the duct removal (in addition to the hood removal cost, if done at same time) and ceiling hole patching, about two-thirds in the roofing patch. If done by a handyman (all work) rather than HVAC and Roofing specialists, maybe as little as half that cost - though unless you knwo the handyman is good with drywall and painting and roofing the work quality might be an unknown risk.
