Wanted: O/T to borrow and a very long shot - film cine camera (TV/Film)

Well, here is a very long shot but always worth asking right?

Against my better judgment I have agreed to help produce a short film. This would be fine except the budget is essentially £0

Does anyone have or know anyone that could help with getting hold of a cine camera for a weekend shoot end Aug/beg Sept. Something along the lines of a Canon C300 or Arri Alexa
Equipment houses I've been in touch with are coming back with rather high quotes.

Obviously we would be fully insured and take incredibly good care of it.

Also looking for accompanying equipment although boom mike, radio mikes and tripod are probably sorted.

1 x Set 15mm bars
1 x Aaton-based Hand-hold rig (as per Aimimage)
1 x Angenieux 15-40mm Optimo zoom
1 x Angenieux 45-120mm Optimo zoom
1 x Set IRND filters 0.3 - 2.1
1 x Pola
1 x O’Connor Fluid head (150mm bowl)
1 x 3-stage medium gauge tripod
1 x Saddle bag
1 x Hi-Hat
1 x Key West dolly & track (approx 40’)

Now I've typed it up I'm regretting my choice
Any help greatly appreciated;equipment, contacts, anything..

Beer a given. You can be an extra (oooooh)
