Simple Arduino RPM Switch

Dear Sir

Can you please give me a quote for Arduino project?

I need 3 rpm limit tresholds to controol speed of a shaft shaft

When the shaft reaches 180 RPM green led lights

When the shaft reaches 200 RPM red led lights

When the shaft reaches 220 Rpm blue lights

The above Rpm linits should be changeable,

The shaft Rpm sensor will be a proximity sensor

Please include wireing diagram.
