I suspect this was an adverts for the estate agents you posted a link to (which was removed!)
Quite frankly, looking for a home in a new area has never been easier.
There is RightMove, Findaproperty and Zoopla all of which will have nearly all properties currently on the market for any area you may be looking to move to.
For those that are selling a home , the internet has made this easy and very cost effective.
There is no longer any need whatsoever, to use a local estate agent and pay them thousands of pounds in return for doing very little.
Why you no longer need estate agents to sell your home.
