Questions for derivative/option traders who are marked as “Professional”

Hi,

Starting Oct.1 I will be marked as a "professional trader". I programmed my very own script to trade option contracts; ultimately, this trades about 100 order executions(or 500 order attempts) per day. I have a couple of question with people with experience with this.

1.) Are professionals still eligible to get price improvement from Market Makers?

2.) What is the fee schedule(monthly and per trade)?

3.) Best Low Cost Broker for high volume trading?

Hopefully someone here has experience with something like this.

Thanks
