Enclosed please find." - This phrase, more than any other in the world of businsss writing, epitomizes the lawyer-like way people start to write when they are either desperate to avoid using a pronoun like "I" or simply love to repeat phrases they've seen in other letters without ever thinking for themselves. After all, what do you have to "find"?
That reminds me of a joke. A guy goes into a restaurant and orders a steak dinner. Later, the waiter walks over table, smiles obsequiously, and asks "How did you find your steak?" The guy looks at the waiter and says, "I just moved the mashed potatoes--and there it was!"
When The Beatles were returning home after coming to the United States, a journalist asked them: "How did you find America?" One of the Fab Four answered, "We turned left at Greenland."
Enough said! There's nothing to "find." Use "enclosed is..." or "I've enclosed."
