It seems odd that the DA told you that you must hire a lawyer to represent you. Unless, they are seeking jail time, it should not be something that was said. Moreover, you could try and correct the mistakes ahead of time, i.e. register the plate so the suspension is lifted and get insurance on the vehicle. If you do that, it may prevent your license from being suspended and the court may be willing to dismiss 1 or both of the charges, since you corrected the problem. If you hire a lawyer, make sure you have a solid understanding of what he/she is going to do for you and what you need to do, to correct this. Anything you are told should be in writing. The $750 seems reasonable for a fee to charge but if you want, you can try and negotiate a lower offer.
