Does anyone know where I can finds or get a copy of a contract of assignment?

Go to a local REIA

@Myles Hendricks  if you plan to treat it as a legitimate business, invest a few hundred dollars in your own purchase & sale agreement and assignment contract, written by a licensed attorney in your state. A good real estate attorney may already have something they can offer you or update as needed, without reinventing the wheel. But you generally don't want to use legal docs from other parties without having an attorney review for your protection. Please keep in mind that you are not selling candy bars or an Xbox on Craigslist or something, you are transacting in real estate that comes with a lot of liability. Don't be cheap and look for free crappy docs online. Best wishes in your journey!
