@Clayton Miller welcome and you sound very motivated!
There are so many ways to structure a deal:
First find out what your investors are looking for. Do they want to be debt (a lender) or equity (a partner)? Debt is safer, but equity will [hopefully] provide more upside. You might get some investors that want to be debt and some want to be equity. In both scenarios find out what returns will make them happy with the deal (some of it is going to be hard to really find out without a deal in place, yet it's probably hard to find a deal without the money in place - so you're caught with the chicken-and-egg conundrum.)
Once you find out what return they are looking for and how much money they will [hopefully and actually] invest, then you can see what the total return is and how much you will make on the deal after you put the numbers together.
The best advice I could give is to gain experience, and that's how you get out of the chicken-and-egg juggernaut. So with that said - and you may not want to hear it - is just get your first deal done with two criteria: 1) Make sure your investors make money and 2) they are happy with your style. If those go well and you make any money on your first deal chalk it up to a bonus, but you got the hardest part out of the way: the experience!
Best of luck and I know it's tough being a newbie, but once you get rolling it gets a whole lot easier.
