Judges in my area will ask you how long you need to pay a ticket and will, within reason, give the requested time. Generally it is up to 90 days. I don't practice in your area, but consider giving this a chance.
The judge has discretion to permit you to pay the ticket in installments, and to forgive the $300 penalty.
PLEASE NOTE THAT THIS RESPONSE SHOULD NOT BE CONSTRUED AS A LEGAL OPINION OR ADVISE, AND DOES NOT CREATE AN ATTORNEY-CLIENT RELATIONSHIP.

It really depends on the judge and the court you are in if you get a payment plan. But, based on what you wrote, you might have other issues. Did you get a failure to appear? That might have added to your fines and might effect your license. An attorney would be able to find these answers out for you, might be able to reduce the fines and resolve any license issues -- if you indeed got a "failure to appear".
