I'd possibly be interested in a carry trade, though I might need to be clear of a few things. Wouldn't you only be making interest on the amount you control? If so, wouldn't a down market eventually take your profits, then account balance, and then give you less interest as your controlling amount goes down with the price? Or is the idea that we will have so much in our account that we can ride through these bears until they become profitable again, and still accrue interest?
What would assure us profit if, say the Aud/Jpy has just reached its peak as we went long, and made a long-term glide down to 90? Would we just wait it out until we were profitable with up-turns or interest?
As to where you might find more potential investors, I have a couple ideas.
www.prosper.com is a site I just came across yesterday. It is a person-to-person loan system. People ask for loans, and others bid amounts and interest rates to loan to them. If people are willing to give those in debt and bankruptcy loans, I imagine many more would give to successful FOREX traders.
Second, there is a huge market in HYIPs (High Yield Investment Programs). Generally, these are all pyramid schemes and other scams, but I've seen some Hedge Fund-ish sites advertised (though I don't know their particular system or legitimacy). You can see a large list at
www.ministryofgold.com
With these two examples, I'm nearly positive you could find the amount of funding you're looking for, since there are A LOT of people out there trying to make an easy (and sometimes very risky) dollar.
