I wouldn’t be open to using escrow for this task as you are not risking any funds and also it would complicate the process of doing the task. The $6.50 also never leaves your ownership. If you are still interested shoot me a PM.
You hire people to do the job, but you want to get the job done and then pay them later. This already requires escrow, otherwise where is the guarantee that you will fulfill your obligations after the people you hired do the work?
To be honest, what you are offering looks like a scam and your offer is unfair.
