Basically, I have a spreadsheet with a list of clients and when they signed
up for their services with my company. Some of them pay monthly and some pay
annually. The company owner wants to see a month by month breakout of the
money we'll have coming in, basically a forecast.

I'm a fairly savvy Excel user, but it's been a while since I've undertaken a
task this complicated, so any suggestions would be extremely valuable.

Thanks everyone!
