I am in a bad financial situation due to IRS

[color=blue][/color]I am in a bad financial situation due to IRS and having to pay off my daughter's student load. I was ok with my creditors until this happened. I am three and almost four months behind with all my creditors who have been calling and calling. I do not call them back because I don't have the money to pay them yet. I won't be able to start paying them until 6/15/05. I am bad with handling money and need someone to help me figure out a payment plan. My total debt is about $2,500. Not more than that. I know this sounds little, but when you have few monies to work with it's a lot. What would be your suggestion to pay off this amount? I can afford to pay $500 per month. Any suggestions would be greatly appreciated.
