Update, I stuck to my guns and they ACCEPTED my bid....
I really feel that it was a fair bid for both parties involved. Now I just need to figure out how to handle publishing / copyright / Usage. In the email I received, I was told to provide ~ 25 images immediately following the event, which will be published in two different company travel magazines.
I guess i'll go back and sift thru this thread, I remember reading a few posts that offered information on the next few steps I need to take. Again, thanks for all the comments....they are all very helpful.
