Paper trading is indeed very different than live trading. What I would suggest is that you:
1- get a series 7 license
2- get an account at a prop firm and negotiate .005 or lower commissions (not hard in this environment). Btw, your current broker is grossly overcharging you now at .01
3- obtain the most leverage available (bright is best for this, but will charge substantial haircut, from what I have read here). Firms that don't charge haircut are obviously the best, but you have to see how much leverage they will give you.
4-trade your system and keep your monthly statements as proof of the system's profitablilty
5- after you have at least a year's worth of records and still need financing, it will be much easier to obtain
However, as others pointed out, you must realize that anyone fronting money for you will expect to be compensated adequately for their risk. Put yourself on the other side of the equation- why would an investor want to give money to an unproven trader and system when there are a plethora of hedge funds managed by traders with years of experience and solid track records returning over 20% per year. Can you show substantially higher returns to justify the risk of the investor funding you??
If you can do it, raise the money yourself and trade prop. until you have a solid track record worthy of soliciting large investments.
