Lang every broker has different regs, as I said I use Interactivebrokers.com Years ago when I opened my account the minimum funding was 10K. I have a large Roth IRA trading account so trading 5 or 10 contracts is not a problem for me. I know of one place you can look into where the minimums are less so here we go.
Fire off an e-mail to Jerry here is his address.

Jerry has a trading room(I am not a part of it) however he has a relationship with a broker if I remember correctly that has lower limits for opening an account,ask him about it. They day trade alot of stocks but I think the brokerage they use also has access to futures. I would start there or simply google interactivebrokers and spend some time on their site. Point and click trading at it's finest IMHO.
