Hey, guys...I posted a while back about how I should charge for contract tech support and the like and got some great advice. One of the pieces of wisdom was that I should NOT charge by the hour for database design (thanks, cyberhh). Well, now I have a reason to apply that (going to be building a db for an old employer in Access) and another question about billing.

How DO I charge for database design? By the number of objects I have to build in? By an estimate for how long it will take me and then stick to it no matter how long it really takes? By the size of the thing once it's finished? I am so clueless (obviously). Help!!
