A few weeks ago I had an idea for a new fiverr gig--writing sonnets. In the past 4 days I have received 2 orders for this $10 gig. Given my mutant vocabulary, I can put together rhymes in very little time, meaning this is an efficient use of my time.
Now I just need to write the sonnets and get high star ratings so this gig will take off like my fashion product description gig did. The key with fiverr is to find things you can do quickly that others cannot/will not.
