Onsite delegate registration - Cheshire

I am looking for someone to welcome and register delegates at a series of one day events held near Chester. You will need to have good communication skills and be personable and professional. Once registration is completed, you will be needed for general on site admin duties around the venue, reporting to a project manager. Hours on site will be approx. 11.00 until 17.00.
Previous knowledge or experience in events is helpful, but not essential for the right person.
Days are intermittent and infrequent (3 in 2011, 14 in 2012 so far).
NOTE: You must be based within 40 miles of Chester. We can not pay travel expenses, and if you live further away you would be expected to stay overnight prior to the event at your own expense to eliminate travel delay risks.
