A Seig X3 would take a single phase input, be as noisy and big as your current plan, maybe slightly heavier but its to your advantage (and its still moveable).

You could buy a manual one and do a CNC conversion if that's the bit that interests you?
Yes Andy something like that.

To the OP, I understand the desire to DIY build and I'm the last person to put anyone off DIY building but in your case with the design you show then it would be a mistake to build as you are not making it any better than a standard off the shelf Mill, infact it will be quite a lot weaker.
To do this correctly and gain any advantage over a standard Mill will require much heavier tubes and bracing of the frame along with equipment like milling machine to help you achieve accuracy. The welding alone of thick tubes will require Higher power welders than your average DIY build will have access to and bolting together alone just doesn't work very well.

If you don't have equipment to help you do this then your just going to waste money and be very disapointed with the end result.

I strongly advise you to Re-think this and look at converting a manual mill like the Sieg X3 etc.
