Networking expert for in-person event

I am in need of a networking guru to assist us with building leads at an event we have in Central London on Monday 12 December between 6pm and 9pm.

We have limited director capability to ensure we work the room properly to secure leads for our digital marketing agency, and require assistance to promote what we do.

Ideally someone knowledgeable in the digital space would be good - but at a minimum the ability to talk to everyone, capture contacts and digest them in to a summary afterwards for our team to follow up. Presentable, smart and intelligent.

This could be the start of other things we can do in terms of sales and business development if this is a success. Wine, beer and food will be provided!
