wind generator/electric motor that can generate up to 15 Kw?
where can I get a cheap reliable electric motor to connect to a wind turbine that will generate 15 (or more) kilowatts with average 40 mile an hour winds.
and I need 2 that get 5Kw going about 2-10 mile an hour (this one will be pushed by water).

$60k, see source. You should build one yourself, most turbines are designed for lower wind speeds which means they use bigger blades and higher gearing. If you have that sort of wind you can use smaller blades and lower gearing, which would save you some money. But at $60k it is still a great investment if you see those wind speeds for more than 40% of the day.
Water turbines tend to be designed for feet of head and gallons per minute, and are attached to a pipe. Depending on how you design the outlet at the turbine, you can get speeds between 0 and 150 mph, but that doesn’t matter, the real question is pressure and how much water you have, not the speed of the water because the turbine does that itself. If you are looking for something that can sit in the tide and generate energy you aren’t going to find something off the shelf, it unfortunately doesn’t exist.
