are there any spot oil brokers out there who don't deal in futures contract, every broker i see is all crude oil futures, any spot oil brokers out there.
Who would want to trade it if there are better suitable for speculators oil futures? Spot would be very illiquid.
my guess is that since you are looking for an over the counter market you are going to have to have more than just the margin that a futures broker would require. supposed to be a pretty large market of actual crude and many full tankers trade hands many times over in transit across oceans. you might be better off looking for employment at an oil company trading desk to learn that game.
