Photography Money Trouble?

I'am having problems with my photography, I can deliver photos I've done a wedding and a few shoots. The problem I have is my job... its very limiting to days off I can have i work mainly like 19-22:30 and various times that end at 10- 10:30. Saturday/Sunday/Monday and Thursday there's NO jobs at all around here and I can't drive and I'd have to get a 15min bus to the closest train station. I can make money from my photography but its limited and far between at the moment. I'am asking professionals or people who make money with there photos how can I not have a job and fund myself for driving lessons etc the minimum i could live off for a month would be about �300 (about $480). I can't do alot of shoots because I can't get the days off to do them which is stunting my growth as a photographer any information on breaking into low money professional photography would be a huge help or just places to easily sell your photos for a steady low income would be much appreciated thank you
