cooperation & cooperate

[ziawj2]

A new friend volunteered to take part in a school project which I am doing. So I wrote to her a letter to accept her offer and express my appreciation. At the end of the letter, I expressed my expectation by writing:
1) We will have a good cooperation.
2) We could delightfuly cooperate with each other.
I just translate the meaning into English. Could you help me to make it natural and acceptable to native speakers? Thank you.

I hope our cooperation will be profitable??

You could just say, "I'm looking forward to our working together." (or grammatically wrong. but more usual - ........to us working together."
