Quick dumb Rock Band 2 question

I know some strategies for this were mentioned in some other thread long ago, but what’s the quickest way to make some money to get new characters for my friends some band-appropriate outfits? Is there a particular challenge I can do or venue I can play over and over again that has a good ease to payoff ratio? Thanks.

According to GameFAQs (the forums, anyway):

Hire the accountant and play multiple song venues in the third location in a city(the big arena).

You can do a 3 song ‘make a setlist’ that includes Charlene, Hello There, and another short song of your choice. Youll be done within 4 minutes and $5000+ richer. Rinse and repeat.

That sounds plausible.

Thanks.

That wasn’t a dumb question at all! You dummy. :)
