N-Gram go getter?

Hi - does anyone have a program where you can enter a phrase and it goes off to google and gets a load of n-grams for that phrase?

Im looking for 1 through 5 n-grams but absolutely anything will do.

Cheers
If not - and anyone can sponsor me to code this job please let me know. Id rather get hold of a working tool though cos its a bit tricky to write.

Cheers again.

google 1T 5-gram available from LDC but it costs $150 and can't be used commercially. i basically decided building my own n-gram database and make it domain specific.
