Hiring and volleying you doesn't earn you very much at the moment. Only 1m per hire, which isn't good, especially when you're so overpriced. What you should do, is try to farm, repeat jobs if necessary for cash, party, do pwars, etc. And try and save up to a certain amount. I'd try saving up to 100-250m on your own, and then speaking to your pupil about what to do from there. Your pupil should be able to give you some farms for your stats, and many more tips than what I just gave you, that are perfectly suited for you, as these are general tips. Best of luck!
Actually depends how much a volley. If they volley her 100 times that's 100m which is about 5 upgrades..
