Day Trading Brokers?

I recently picked up day-trading as a hobby and have actually been doing fairly well. I previously had an account with Trade Kings but they suspended me from day-trading because i did not have 25k in my account. I do not have 25k to invest at this time and want to continue day-trading. Does anyone have any suggestions for brokers that I can daytrade with where there is no minimum balance required? Please advise.
