Looking for a laptop/notebook with certain requirements

Hi, Simply put I'm looking for a laptop that meets these minimum requirements:
Windows 7, Windows 8, OS X 10.8 Mountain Lion, OS X 10.9 Mavericks or OS X 10.10 Yosemite 64-bit operating system 650MB free hard disk space for installation Internet connection required for activation and web services Intel Core i3, Core i5, Core i7 or Intel Xeon (Nehalem) processor or AMD equivalent 4GB RAM OpenGL 2.0 graphics card with at least 512MB video memory (NVIDIA GeForce 9 series, AMD Radeon HD 5000 series, Intel HD 4000)

It's so I can run Hitfilm Express, I'm trying not to mess this up so are these common, or do I need a suggestion? Thanks

I think most laptops on sale by PCS will satisfy those specs. To get better advice, you should give a maximum budget you can spend and what else you want to use the laptop for.
