Investing and receiving royalties

[Corey Stewart]

Hi there, I have a new opportunity to invest in a company and receive royalties on every product sold. I don't have a lawyer as of yet but need the documentation so I can move forward. Does anyone have any suggestions where to start?

I have already vested the company and they are all set, no debts, nothing outstanding, litigation etc..

I will receive a percentage of the company as well. % is dependent on the investment size.
