Props needed for my Thriller Opening Sequence

Mise-en-Scene inspiration for the props:

Research as to where we can get the props:

• Knives - prop knives are easily obtainable from online shopping websites (such as Amazon). They cost, on average, about £3, although we'd need a few of them.
• Rucksacks - backpacks and the like average at about £10 - £20, but most of our group already have black rucksacks at hand so we can use them for free.
• Netting - thick netting would cost about £10 from an online website.
• Padlock - a padlock costs under £5.
• Polaroid - we'd only need one polaroid photograph, which would be easily arrangeable without costing any money.
• Maps - a couple of maps would be easily obtainable from asking the Geography Department.
• Petrol Canister - our teacher is able to provide us with a red jerry-can.
• Baseball Bat - a baseball bat would cost about £20 but some of our group happen to have some that we can use.
• Hockey Stick - a hockey stick is about £15, although the school have some old ones that we can use.
• Nails - nails would cost about £5 for a large number of them, although the school can supply us with them.
• Barbed Wire - barbed wire is under £10, although once again obtainable for free through the school.
• Chainsaw - this would likely be our most expensive purchase given that it averages at about £80 in price. However, if needs be, we'd be able to take it away from our sequence... With that said, the maintenance staff at school have said that with permission and supervision we'd perhaps be able to make use of theirs for free.
