What are the job types for company finances and their saleries?

I'm working on a business plan and I want to hire people to take care of financial and legal sort of things in my company. What are the types of people I need to hire? And how much are their yearly salaries? [serious answers only, no criticism please]

in my company; type of company?

if you wish to start a company, attend at least one class in management and small business

a salary offered is based not on the basics of the local demand but on what the company can afford.

do research and write a biz plan
