You are looking in the wrong places, the people you want already have jobs but are being treated badly and are under appreciated.
I have been asked about jobs numerous times by the staff in the coffee shops I frequent ( Neros, Costa) they all Complain about being treated like poo, long hours.... they start at 6:45am and finish at 7pm they get 30 mins lunch which often they are too busy to take.
Most hate thier jobs and are looking for alternative employment, I know this as fact as my son works for Costa coffee and he tells me most of his workmates are unhappy, he hates it and constantly as for his old job back with me
