"Small businesses" is not an audience. You can't find five of them by Monday, because you don't know where to look.
Describe the person, not the market
A good audience names a role, a company size and a situation: maintenance leads at factories with 20–100 staff that run their own machines. Now you know which job titles to search for.
Keep a research column
New leads start in Research. Add a line on why each one made the list. If you can't write that line, they probably don't belong in this test.
Stop at five
The quota is a ceiling as much as a floor. Five good leads beat twenty rushed ones, and you'll pick five more next week.
