Staff Approval Notes:
It is a common SE method to a source that i haven't seen before and may actually be much more usable then the common places as it comes with an outside source. For the price point you're getting pretty much what you pay for and may be re-usuable as i see no reason why it can't be also a phone call is NOT required meaning it can be used if you aren't intending on going that route. The OP also shows you a chat log of one of his SE's of using this method which may help alot to go off of.
Good luck!
