I work for a gym and sports centre called Maidstone YMCA. Have spoken to my manager to see if she can do a price for you. Please let me know of any interest and ill be able to give you a figure. It's based on a minimum of 4 people joining. We are a brand new centre, have state of the art equipment, and have 3g external football pitches to hire as well.
(not sure if this is suitable for this section)
