Suggest 5 potential MVPs I could design and deploy

The MVP is to confirm market demand. 
Each MVP idea should be fast (<1 day) to deploy, cost less than $100 and have a success/failure condition.

Each MVP should be sequential, following on from the last, from smallest to largest commitment to create and deploy. Each should only be deployed if the previous success condition is met. 

Provide the 5 MVPs and a basic flowchart decision tree.
