You need to find out what the requirements are in your area. You’ll want to know what the regulations require, what rent for facilities costs in your area, what supplies you’ll need and what they will cost, etc. This is going to take some homework in your area to figure it out! Think about what age group you want to work with. Will you need cots? Diapers? What kind of toys? What kind of sanitizing supplies will you need? What will the utilities cost? Will you buy art supplies for the children? A television and DVD’s? A computer? Will you need CD’s and something to play them on? What kind of licensing fees will you have to pay? There’s a lot to consider. Maybe the best way for you to figure this out is to keep a notebook and calculate these expenses individually, then add everything up and tack on some extra for whatever you forgot! Then you should have a fair estimate of what it would take to do this. Are you going to borrow the money to do this? I would think whoever is going to finance you would be impressed if you took the time to note all these possible expenses and what it would cost to accomplish this.
