In general there are two sides to this. You need to establish a trading strategy and verifiable track record that is marketable. Then after or concurrently, you'll need to start a business. The business side of the hedge fund will include at a minimum:
-Lawyer (establish your GP, LP, investment manager,investor agreements and do any filings that are necessary)
-3rd party Administrator (Keep track of you P & L and cash movement)
-Auditor (Check books and records for accuracy)
-Prime Broker (clear and custody positions and cash)
We are called a mini-prime or introducing broker. Most importantly, we offer an introduction to the Prime Broker and provide trading platforms and access to the exchanges. However, we help coordinate the needs of all of the above.
When an investor invests as a LP in a hedge fund, they expect to be investing in a business, not just a person.
