Could this really cause a short supply?

I would like to take a look at what they are using as a reference myself if at all possible since from what you are saying it plays a huge role.Answer - Consultants obtain their pricing from many sources (experience, online, supply/demand, etc.), just the same as where contractors obtain their prices.
