I think here they hire at 15, but I cant see them hiring and training you now. It usually only takes a few days to train for ajob like that, so 5 months of training would be a bit overkill.
My suggestion, if you are looking to work right away, is check with the local grocery stores. Here they will hire you at 14 to work weekends as baggers.
If no one there will hire until 15, you'll have to reapply on or after your birthday, or maybe a week or two before. They might be able to do the interviews and drug testing before you are 15, but you wouldnt be able to start work until your 15th birthday.
Good luck!
