Quick Turn Around Time...

I've got a really good client who has more frequently been asking for quick turn around times on projects. For instance, last week I had to shoot an interview with an executive, then do all the editing that night so they could show the clip the following morning.

Now I've got a 3/4 day shoot planned for them on a Thursday (shooting a tradeshow event), and they want to show a finished highlight video (3-4 minutes) on the following Monday morning. As the editor (and one of the shooters), I know that going through all the footage, finding music, creating graphics, etc. is going to take some time - not to mention the revisions I'll get from the 5-6 people who review the video (most likely at 3:30 or 4 on Friday)...ah, corporate video!

And I really don't want to work over the weekend...did I mention I've done it the last 2 weekends on other projects for them?

As a new small production company owner, how do the rest of you all handle these type of situations? This is without question my biggest client, and I want to keep them happy. But I also don't want to get taken advantage of. They produce a lot of videos and I know they use other companies too, and I'm really wondering if they all bend over backwards to make these kinds of deadlines. Should I bring up a rush charge?

Any input or advice would be great.

Thanks!
