Unfortunately, with hedge funds, you cannot use any prior track record from a prior fund or personal trading (even if audited). So if you are a famous fund manager you will raise all you want off your reputation because everyone is aware of the returns you have generated in the past, but you still cannot use them to market your new fund. So if you are a famous prop trader I imagine it would work the same way, with less capital. As far as an audit goes, the minimum from a top name firm is 30K, usually per year. It is so expensive because of their liability supposedly. But it would be a waste of time anyhow since no one (institutional) really gives a shit about a track record with less than 40M, and wouldn't even look at a fund with less than that, even the FoF looking to invest in small time start ups don't look under 10M. So the first many millions are all up to you impressing people you know enough to contribute and building a track record in the fund. The problem with start-ups that have little capital is the expenses of audit/tax/legal. But even then if your fund lays down an audited track record that is a better risk/reward than 90% of hedge funds then your fund will grow nicely over time. If you don't know anybody then the only way to get noticed is to perform better than everybody. That is not easy to do.
