Service providers for emerging hedge fund?

I was wondering if you guys have any suggestions for respectable fund administrators and custodians who are friendly to small startups (regulatory regime: U.S fund management company, U.S.-only investors, mostly futures and commodities)? Our AUM just falls short of justifying the costs of the typical names or of being taken seriously by a typical PB, but we're in the tricky stage of needing to define the key service providers to proceed on the business-end.

I found several suitable brokers that might provide prime custody services to a small firm for the equity space. On the other hand, the commodities space seems to be left with 2~3 who target emerging HFs now that MF Global is gone.

Also, does anyone have any comment on the execution quality in CME using Newedge colo? Have to provision for 10^7 RT $10^-6 year^-1, not exactly high volume stuff but still latency-sensitive. Dare not ask about direct connection to Globex since we probably can't afford the initial capex.

Thanks! :)
