Please, please, please tell us that this is "just something you want to do" and you don't hope that it will get you closer to a job. Otherwise, I would second Can737's sentiments.
When I used to hire pilots, a rating without experience only ever indicated trouble. It either meant the pilot had jerked another company around and was likely to jerk ours around or had paid for their rating hoping it would get noticed. Considering you can never tell the difference between the two situations, such a resume was filed in the bin beside the desk rather than the one on it. If this is what you hope, save your money for the gas and drive to find a job.
If, however, you're doing it just because you want to, then have a blast.
