I have put together a large bid, larger than what I usually deal with and for the first time I am representing a group of people, with higher expertise than me.

This is something that could provide us with work for years to come.

How are such things usually managed? It was sent in last week but I haven't heard from them since. The person in charge was away.

When I finally reached him, he told me that I would get the O.K. in a week but also that he was not the final decision-taker.
I have not been able to reach the final decision-taker and I do not want to come across as frantic but keen.

Any advice?
Any good books on leading negotiations.

One very good piece of advice was to come across as very reassuring and not leave any doubt on the final performance.
