Exactly. As for the air issue, there's no way a single dive tank would provide air for 10 people for a day. You'd need at least 3-4 dive tanks.Nice to see you've thought this through.
Contact the people noted above and chat to them about things like air, paint, toilets, refreshments, insurance, administration, etc.
thanks for that i will keep that in mind marshalls not a problem i know a couple plus it wont be a seriuose event it would be pratice for most people but just a good day for my birthdayFind a venue, if you pick a date when I am free, and if you need it, I can provide Air and a Millennium Field for £400 (+VAT) per day plus expenses. You provide labour to get the field put up and packed away.
I will need to be satisfied that the venue is safe and legit before committing.
If you want full event management including labour, refs, toilets, staging, ect, the price goes up.
There's an option for you.
