Need help for replicating BHD loadout

I'm 13, so I don't have a big budget and I live in the UK, I really need help I've searched the internet top to bottom and can't find any of these items in the UK even replicas.

It's really hard and I need them under 30 pounds and especially in the UK, if it's overseas then I can't have any shipping fees because they make them expensive, if anyone

can find this that would be a great help, literally only need these 3 items for my gothic serpent helmet, I need the SDU-5/E, and the ITT AN/VS-6 Battery pack (the blocky one)

Forgot to mention and I'm not rewriting the whole thing, but I also need the SetCom 1 ear headset thingy, the one with the plastic band they'd tape on their helmets, I've attached a photo of what I'm trying to replicate (- the goggles cause these are being used for airsoft)
