The maximum amount of time you could serve in jail is the remaining time you have on probation or 2 years in jail whichever is less. However, I don't see either of these scenarios happening. It would be a good move for you to hire a local attorney who is familiar with the court you are in, and who is familiar with the judge who will be handling your case. The lawyer will know specifics about whether the judge is more likely to say give you community service, etc. instead of jail time, and what steps can be taken to better your position when you go to court.
