not going to be the most convincing data to people who look at it every day but probably a good starting point
Awesome. The only tweak I would suggest is to make the data slightly less realistic. It may cause occasional panic attacks unless the name is like "Rupert TESTES Rupertson".
Not sure where we should deploy this, sounds fine to check into the CRM repo, maybe you can create a new module for this stuff, we can eventually expand it into a more featured test data generator, and exclude from the production branch.
