Need some steel parts cutting/machining, fairly quickly (UK)

[R9000]

Alright, so I was thinking of just ordering from some company online, but I know we've got a few people who work with metals here, so I thought I'd ask around. I need some 5mm, 4mm and 10mm steel cutting or machining from some 3D part models, preferably within a week or less. You can get an idea of what I need on my build diary thread here, but if anyone can do this I'll send some proper CAD files and such, since those were only made in Sketchup. Most of the metallic-textured stuff you see there I'll need (other than the nuts, axles and side-plates, I can do those on my own). If you have Hardox (or even Titanium for the shovel), I'd like to use that instead, but I've no idea what availability's like at the thicknesses I need. That said, I can just use mild steel if that's all that's going. Could probably do with a rough idea of what these kinds of parts usually cost, as these aren't super complex.
The reason I say quickly is that I'm trying to get this thing built over the Easter hols, and I've got less than two weeks left. If it takes longer, it'd probably still be ok, but not ideal.
Cheers guys.
