At the risk of sounding excited

Hi,
I have difficulty in understanding the last part of the conversations below (underlined ):
I’d appreciate any help.
(Karen and Andrew are from Company X, Sean and Francoise from Company Y)
---------------------------------
Karen: We’ve discussed this problem of logging support and project work, and we’d like to make a proposal.
Sean: Let’s hear it.
Karen: Firstly, we do understand your concerns about the pricing systems. Level A is too expensive and Level B holds too many potential surprises. So, we propose a level of support between A and B. We include all maintenance and support work at a fixed price, plus a minimum project load. How does that sound?
Sean: Good, in theory. But I can’t see any difference between that and Level A. We want to agree a monthly rate for essential support and project work.
Karen: What about urgent, additional work?
Francoise: You could quote for that when it’s necessary.
Andrew: Wouldn’t that be difficult to manage in reality?
We could get delays while we waited for your approval.
Karen: How would it work, Francoise?
Francoise: Maybe we could agree a contingency sum at the start of the year to cover urgent projects.
Karen: Would the IT Manager have control of that?
Francoise: No, but I’m sure I could approve most of the work myself.
Karen: At the risk of sounding excited, that could work.
Andrew: Let’s go back to the original proposal and put some figures to this.
Sean: Great. Let’s get started.
--------------------------------------------------------------------
The underlined part does not make much sense to me. Could anyone please paraphrase it?

Thank you in advance.
