Mainstream brokerages will do this starting at $2,000. You just apply for margin and take out the cash. Of course if the value of your stocks drops below $2,000, they will start selling stocks out from underneath you and triggering capital gains. The real use of margin is that it enables the holder of the stocks to use them with the broker to take on cash obligations in the form of other stock options, or to take on obligations which require holding certain shares which create cash, such as a short call option.
