We work with a smaller crew (4-7 people), we've shot six features in six years (and the director has DP'ed other features during that time), all of which have seen national distribution, and all of which have paid themselves back in time.
I wouldn't call them mainstream successful, but we get attention by name magazines and websites.
Are we making a lot of money? Nope. But I consider our movies a success...at least on a smaller scale. And in terms of local clout, we are known by the majority of filmmakers as being one of the only company that sells our shit.
To be completely honest...I think large crews screw up independent film making. On larger budget films it works fine, because people either get their job done, or they get fired. On micro budget productions, a large crew slows things down...there is a lot more bullshitting going on, people aren't sure what they should be doing, and there tend to be egos...
I mean it when I say our sets run more smoothly than any set I've worked on, and we have so few people working on it (even us actors are crew). We can shoot 10 pages in a full day if we bust our ass...and that's with a lot of coverage.
I really am not bragging here...I'm being forthcoming to answer the OP's inquiry.

The director is Richard Griffin of Scorpio Film Releasing. Yes I'm bias...lol. Sorry.
