Ok. Assuming EVERYTHING else was in proper order.
ok heres my question. would i be able to hire people to run each cart at each location?
I do not think the "splitting the profit" philosophy would go over well, with a new business. You assume an average of $300 a day. I do not know how you got there. However, there is no way to guarantee $300 per day, from the jump. What if, the first week, you sold only $50 worth of business? You will find yourself with plenty of turnover, as far as employees. I do not know what the employment guidelines are, for your state. You have to guarantee at least minimum wage, here, and not many would be motivated for that deal.
meaning would it be worth THEIR WHILE to "work for me"?
That is entirely up to THOSE people, as individuals.
but wouldnt that person just feel they could eventually do it themselves and make double the money?
Sure. That is how you got here, no?
Paper is magical. Eveything on it, looks so good.
