Proposal for my film

For my media project I need to make a trailer to a horror film, it will be influenced by iconic modern horror films such as Paranormal Activity, The Children, Woman in Black, The Conjuring and The Unborn.  Even though it is just a trailer I am making, I will still need access to my schools MAC computers in order to put it all together so it isn't just random clips mixed in together. The MACs will help me more than a normal computer because it already has the software that I need to make it work, software such as: Final cut pro, imovie and Photoshop (in the trailer I am planning to use old images in the times where the young girl was still alive, here I will photoshop the little girl into an victorian picture either found on the internet or taken myself with a few effects). Due to my story line, I will need to find a building that is like an apartment or flat-like that seems quite old to the audiences eye, but suitable for "University students". It needs to have rooms big enough for the people that will be "living" there and easy to move around when filming my footage. With using a building of that description, I would also like to have permission to move things around in the rooms and change some of it's style in morder to make it look refurbished from an old victorian flat-like building.
The cameras and the use of a tripod is not a problem, because I have my own access to a fuji camera, a cam-corder (which I will ask to borrow from my school) and my own tripod so the non-shaky footage will seem professional.

I already have my actors, due to them being every day teenagers, my friends have kindly volunteered to be a part of my project. I already have use of "extras" as I will be needing more people in a particular scene where a "house- warming party" will be held.
The only things I haven't got yet is the props, which will basically be old children's toys, frames, hopefully a rocking horse- or a rocking chair. I may be able to find these props in a local charity shop, online (ebay.co.uk) or in a little trinket shop. Another option is asking to borrow my friends sisters toys as they seem modern, but also old... I am not sure on this idea and on how it will fit, but if it works, then hopefully the toys will be added in, however the charity shops will be a saver option of getting old and tatty children's toys. A few other props I will need a few glass bottles and plates in order for them to be smashed at the party scene along with an old case that will hold the pictures that someone stumbles across of the young girls life, suitcases and a few cardboard boxes.

Unsure of when I can start filming, I have asked my friends to keep a window open for when I will need them and where they will need to be, which according to them hopefully wouldn't be a problem.
