What are they going to do for you, that you can't do for yourself (besides make $50 - $75 bucks for each trade they place out there, untill your $5000 is gone?)?
Trading firms get a bunch of kids out of finance college and put them to work in a "boiler room" with prosect call lists. You are likely a prospect - - -  - - 
If you don't understand or can't do your own marketing (speculating or hedging) I would not suggest giving someone a bunch of money to do "marketing" for you.
Most markeing firms will "advise" this trade or that trade/spread, they could care less if the trade makes you money. They make money on handling the trade. The more trades they make, the more money they make. They don't make a % of your "winnings"  . . . .  .
