becoming the candy lady tips for advertising and employing

I am the new candy lady in my apartment complex. I am into it but I'd like to expand. Right now the business is pretty new, so I make $5 a day. I am a student, so I cant be home all the time. my target market is kids, but id like to have employees, like girl scouts and such, to sell directly to the public.
Also, im not to sure where to buy the stuff from. I get snikers, oreo bars, hersheys, and m&m's from Kroger for 50 cent and sell for a dollar, but its not enough to have employees. any suggestions
