The challenging thing about freelancing is trying to convince customers that they're solving the wrong problem. Companies generally don't need another flex/php/.net/python/ruby expert, they fail to understand that they need to adhere to software development standards. The old chestnut, "We're not a software shop" never gets old.

Once you actually define the problem enough to put it into a "challenging" category, it's already been solved. The challenging part anyway. The rest is just doing what's already been set out. Very rarely will you hit upon a company that admits, "you know, if we just scrapped everything and start over with TDD and CI we wouldn't have any problems."
