After almost a year and a half of trying to sponsor workers myself...I decided to call it off as a bad joke and buy them instead. That way you get many (depending on how many you order) and so there are more chances of finding at least one or two who will be ready to work along with you. Its more motivating when you have a few workers under you - so my sincere advice to you is buy your PSAs and advertise your sales instead. :)
