Can a broker arbitrarily penalize an independent contractor based on varying factors, such as the sales agent's difficulty in closing a deal or failure to produce paperwork in a timely fashion?

No

Explanation:

An independent contractor is a business person or entity who works for an employer based on an agreed-upon contract which affords him the flexibility of choosing how and when he accomplishes a task. The employer has the right to control the results of his work but has little or no say on how and when the job is done.

An independent contractor is not bound to work specific hours dictated by an employer. When the sale's agent finds it difficult to close a deal or is unable to produce paperwork in a timely fashion, he cannot just be arbitrarily penalized by the broker. The broker could terminate the contract if the agent does not meet up to his requirements.

it's actually a very difficult task, due to not many people can make 2 million dollars in 2 years. besides that, to the not-so-realistic ideas, you can create a business. it could be practically anything, but make it into a business that isn't that known yet, you get me? also, lets not forget about stock market. that's where all the good stuff happens. use investments at the beginning and begin to raise up your business or whatever you're going to do. as this is a very non-realistic idea, it's still worth the shot!
