Interesting that the 501st was brought up. There are
quite a few Furry
costuming groups that do paid or
charity gigs, it's just that they aren't linked together like the 501st is. Sadly, they tend to distance themselves from the fandom (or simply avoid mentioning it) since the mere association with something-that-might-possibly-be-sexual-part-of-the-time-to-some-people is enough for these groups to lose most of their clients. :/
