Hi T,,,
I'm sorry to say this, but I hate posts like this...(A parent asking for work for their child),,, IMHO your son should be asking this question as it shows that he has some get up and go and wants to get on in life rather than their parent pushing them to find a job.
I know that it can be difficult sometimes, as a parent watching them from the sidelines and encouraging them to do things but that is just as it should be..
Anyway,, as I'm in North Wales I'm of no practical help,, but I hope that your son finds work and wish him all the best
