Arduino interrupt for anemometer

I need a velocimeter to measure the wind speed using an Arduino Mega 2560.

- As sensor I have an anemometer that send a positive pulse every 220mm (or 2 pulses per revolution where the radius is 70mm).

- I'm using the Arduino Mega 2560 with Ethernet Shield. On Ethernet Shield I'm only using the SD card.

- I'll write to a file (SD Card) the current wind speed every 10s so this is the sample rate.

- AttachInterrupt (Rising) must be used once I'll do a lot of things between the sample of 10s.

- I'm using pin 2 (Servo Motor), and also pins 36 to 53 as I/O's.

- Please only bid if you KNOW how to use interrupts and keep time to process other things.

- Less dan 1 day to do it. You need to let me know the pin to be used and send me the code. The payment will be done if the code work.
