I strongly recommend that you hire a lawyer, or, at the very least, get a public defender. Attorneys are trained in the rules of court procedure and can negotiate with the state attorney on your behalf. You probably won't have any luck doing this yourself. There's an old saying: he who represents himself has a fool for a client. Do yourself a favor and get legal counsel NOW!
Sometimes courts order restitution, but reserve ruling on the amount of restitution owed. They do this just in case victims come forward at a later date and claim damages. If that's the case (and there's no set amount), you don't owe anything as of now. Is what happened to you?
The short answer is ABSOLUTELY. A grand theft charge, especially id you are convicted, can have lasting effects on your professional life. I highly recommend you retain an experienced criminal defense attorney in your area immediately.
A private attorney generally has less clients than a public defender and may have more time to devote to your case. Public Defenders do the best they can under terrible working conditions.
