I dont think too many will complain about more money if it is possible; though I dont think they will turn down the current offer either.
If you are going to ask for more, might I suggest that you make a counter offer of the 1000 plus a set amount per Cruniak head, or better yet ear.
Hey my character might not care about money but I wouldnt mind having them have it.
Lets see how it plays out.
