Hi,
The Open Sure Signal plan is designed more for communities rather than businesses, so I don't think you would qualify.
Depending on the design of this area, I would think the Sure Signal is worth a try ..... if it's an open plan area and the Sure signal was placed near the centre of the area I would have thought it would cover most if not all of it.
The down side of this is that the Sure Signal can only accommodate a maximum of 8 users at any one time, but that is dependent on a good Internet connection and every user ( up to a maximum of 32) would have to be registered onto the system, not really ideal for visitors etc.
This could be a better option for you when it becomes available later this year ..... http://www.vodafone.co.uk/our-network-and-coverage/what-makes-a-great-network/wi-fi-calling/
