If you're Australian, and assuming you have a relevant bachelor's degree, the E3 visa is trivial to get, and to maintain.
It has basically zero cost or effort for the employer: just need to get a Bureau of Labor statement that the offered salary is above market rates for role and location.
It sucks a little for the holder: you've got 10 days to leave the country if your employment ends, and you need to demonstrate every two years that you don't want to remain in the US permanently (yup, that's proving a negative). The renewals seem like they're pretty automatic, but the criteria aren't public and if the decision goes against you, you've again got 10 days to get out.
You don't need a lawyer to get an E3, but once you've got enough cash flow, it might be worth it for renewals and the potential for an appeal if your renewal (technically a new visa issue) is rejected.
